■ CIFS share configuration for Windows file access
The Common Internet File System (CIFS) shares configuration controls
what can connect to the shared drive, based on the user ID and group or
groups. This configuration is necessary for Microsoft Windows NT,
Microsoft Windows 2000, Microsoft Windows 98, and M i crosoft
Windows 95 operating system clients.
For information about CIFS share configuration see “CIFS Shares” in
Chapter 3, “Windows File System Administratio n.”
UNIX and Windows NT Multiprotocol
Environments
■ CIFS share configuration for Windows file access
The CIFS shares configuration controls what can connect to the shared
drive base d on the user ID and gro up or groups. This co nfiguration is
necessary for Windows NT, Windows 2000, Windows 98, and
Windows 95 operating system clients.
For information about CIFS share configuration see “CIFS Shares” in
Chapter 3, “Windows File System Administratio n.”
■ User and group mappi ng configuration
When mapping UNIX users to Windows users with Services for UNIX
(SFU), the Username Mapping Server m aps the group ID (GID) to a
Windows NT group using the group mappings, and the mapping server
maps the Windows NT user ID to a UNIX user ID. The Access Control
List (ACL) determines access, file owner permissions, group owners
and permissio ns, and ot he r user pe r mi ssi ons.
For information about this config uration see “User Name Mapping” in
Chapter 4, “Integrating UNIX into Windows NT.”

Compaq SANworks Virtual Replicator
Compaq SANworks Virtual Replicator (SWVR) provides advanced,
centralized storage management capabilities in Microsoft Windows NT and
Windows 2000 computing enviro nments. Inn ovative storage management
features simplify storage confi guration and manage ment, and enhance
availability and scalability.
SWVR gives you manageable storage tools:
■ Pools—form storage units from hardware arr ays or physical drives
■ Virtual disks—divide pool space of any size, up to 2 terabytes
■ Snapshots—make instant c opies of the virtual disks
■ Online volume growth—increase the size of the virtual disk
Page 42
Administrative Procedures 2-13
Storage Pooling
SWVR enables the group ing of hardware array storage, or physical drives, int o
a logically proportioned pool of drive space. You can create any number of
pools, using industry-standard storage components and controller-base d,
fault-tolerant drive arrays (such as SANworks RAID arrays). The logical
drives created from the RAID arrays are referred to as storage units. The
storage units provide drive space for the pool in the same way that physical
drives provide drive space for a SANworks RAID array.
Virtual Disks
SWVR controls how data is stored on a virtual disk. The virtual disks perform
and behave in exactly the same way as physi cal drives do. You can format and
map drive letters to them, and read from and write to them. Disk virtualization
allows you to optimally tailor drive space to the size required by users and
their applications. You can make the sizes of the virtual disks match the
requirements of your applications and use rs. For example, if a user needs
650 MB of drive space, you can create a 650-MB virtual disk. If you have a
terabyte database, you can combine several drives or SANworks RAID arrays
into a single pool and create a 1-terabyte virtual disk that spans that physical
storage. The size of the virtual disks that you create can range from 10 MB to
1 terabyte, depending on free pool space and other limits set at the time of pool
creation. The TaskSmart N2400 appliance has a maximum storage capacity of
2 terabyte s, which can consist of up to two 1-ter abyte virtual disks. See
Chapter 6, “Advanced Administrati ve Procedures,” for more information
about virtual disk s.
Snapshots
SWVR lets you make insta nt replica s, called snapshots, of virtual disks in a
matter of seconds. Snapshots enable the instant creation of multipurpose
virtual replicas of production data without having to physically copy the data.
Snapshots function in exactly the sa me way as ordinary physical drive s with
read and write capabilities do. S napshots should be co nsidered temporary in
nature. See the “Creating an d Schedulin g Snapshots” section later in this
chapter for additional information.
Page 43
2-14 Compaq TaskSmart N2400 Administration Guide
Online Volume Growth
SWVR provides the ability to increase storage capacity without disrupting
operations on Window s 2000 systems. Normally, when you grow a RAID set,
the operating system does not recognize the size change until you restar t the
system. The SWVR online volume growth feature directs the operating system
to update the size of a physical drive or virtual disk without requiring a system
restart. Online volume growth also can instruct the operating system to grow
the on-disk partition information for a volume. This feature allows a volume to
grow into unused space made available by either increasing the size of a dri ve
or by deleti ng one or m ore adjacent partiti ons. With online volume growth,
you can easily increase storage capacity as required by your users and
applications, and do it with zero downtime.
The online volume growth feature operates only on basic and virtual disks
formatted with the New Technology File System (NTFS). It does not work
with dynamic drives. Chapter 6 provides additional information about SWVR.

Creating and Scheduling Snapshots
Snapshot Overview
Snapshots ar e copies of t he data that is saved on vi rtual disks. Snapshots
initially take up very little space on the hard drive and can be created in mere
seconds. Snapshots are extremely beneficial. They can be used t o immediately
recover a lost file or di rectory, t o t est a new a pplication with important data
without affecting the “real” data, and as a source of data for backups.
Snapshots are a temporary backup of your data and are not meant to be a
permanent form of the data.
Snapshots work by mapping blocks of virtual disks and i ntercepting virtual
disk writes. Each initial write to a data block on the virtual disk causes that
write to perform a copy of the original dat a before replacing it with the new
data being written. This action is known as a copy-out and preserves a copy of
the virtual disk as it was when the snapshot was created. The copy is available
until the snapshot is deleted.
When using snaps h ots, per f orm anc e of the vir tua l disk ma y be aff ec te d,
depending on the rate that your data is changing and the number of snaps hots
kept for each virtual disk. Read performance of the virtual disk remains
constant, regardless of the presence of snapshots. Read performance of the
snapshot is identical to that of the virtual disk. Write performance, however,
may vary. Each initial write to a virtual disk area causes a copy-out to the
snapshot, and the initial write is slower than if a snapshot is not being used.
Copy-out is not performed on subs equent writes to the same virtua l disk block,
so write performance is unaffected after the initial write to each block.
Predicting the exact effect of snapshots on any particular virtual disk is
difficult, because several variables are involved. These variables include the
type of applications accessing the data and the rate of change of the files on
the virtual disk. When a high percentage of writes is made to the same area, as
when a file is constantly rewritten, the area is called write locality. Virtual
disks with high write locality e xperience l ess performance deg radation due to
snapshots.
Page 45
2-16 Compaq TaskSmart N2400 Administration Guide
Snapshot Facts:
■ Snapshots are created on a per-virtual disk basis.
■ You can create up to 12 snapshots per virtual disk.
■ You can create snapshots of snapshots.
■ Snapshots can be read-only or read-write.
■ Snapshots must be assigned to a drive letter to be accessible.
■ Snapshots can be shared in the same manner as virtual disks.
■ Snapshots are meant to be temporary in nature.
■ Snapshots are automatically deleted if pool space becomes critical.
Creating Snapshots
Snapshots are a daily ma i ntenance tool for your TaskSmart N2400 appli ance.
Before creating a snapshot, the TaskSmart N2400 appliance must have a pool,
or pools, of space and one or more virtual disks es tablished. The
TaskSmart N2400 appliance comes preconfigured with pools and virtual disks.
Verify that there is adequate free pool space to support snapshots.
IMPORTANT: Snapshots are temporary in nature and are automatically deleted by the
system if free pool space becomes critical. Snapshot data loss can occur. See “SWVR
Lifeguard Service” later in this chapter for more information.
Chapter 6 provides inst ructions for altering the preconfigured snapshot l ayout
for your work environment. Ins tructions a lso include the procedures required
to create pools and virtual disks.
After the pool or pools of space and one or more virtual disks are established,
the process to create snapshots can begin.
1. From the TaskSmart N2400 con sol e, click Microsoft Management
Console, and then click Disk System.
2. Click Sn apshot Manage r. Then select and click the desired pool.
Page 46
Administrative Procedures 2-17
3. Select a virtual disk.
Figure 2-8. Snapshot Manager screen, creating snapshots

4. Right-click the virtual dis k, click New, and then click Snapshot. The
Snapshot Wizard opens and leads you through a series of questions.
Figure 2-9. New Snapshot Wizard screen
5. Click Next. The Snapshot Information screen is displayed.
6. Enter a name for the snapshot.
NOTE: Appropriate snapshot naming and volume naming must be used to identify each
snapshot individually.
7. Click Next. The Drive Letter Assignment screen is displayed.
8. Click Map Drive Letter and select a drive letter. Enter a volume label.
The default is the same volume label as the virtual disk. Optiona l ly,
click No Drive Letter.
NOTE: It is not necessary to assign a drive letter to the snapshot until you need access to
the snapshot. However, if you plan to create one snapshot per virtual disk, it is advisable
to assign a drive letter at this time.
9. Click Next.
10. Click Finish.
Page 48
Administrative Procedures 2-19
Snapshot Access
■ Snapshots can be read-write, and if they are shared, users can access a
snapshot and edit the data. If snapshots are shared with write access
enabled, it is recommended that a snapshot of the original snapshot be
created. There is no backup of the original snapshot unless a snapshot of
it is taken. By controlling the share permissions, admi ni str a tors can
make snapshots read-only as an alternative to creating snapshots of
snapshots.
NOTE: Snapshots of snapshots can impede performance when both snapshots are
running on the same virtual disk.
■ The parent- child relationship of snapshots of snapshots is not
maintained on the server. Appropriate snapshot naming and volume
naming must be used to identify each snapshot individually. For
example:
G Name the parent “Snapshot A”
G Name the child “Child of Snap shot A”
Snapshots and Backup
Because snapshots are quick to create, it is possible to capture a coherent view
of the virtual disk data with little or no application downtime. Lack of
application downtime removes the traditional backup window or the amount of
time taken to back up to offline media. While many applications must be shut
down to cap ture an acc urate backup, snapshots capture a point-in-time view of
the data that can be use d as the source of backup data. Applicatio ns can
continue processing against the virtual disk data. The refore, applications may
only have to be interr upt ed for a few seconds during the snapshot proce ss.
CAUTION: Snapshots are not a replacement for reliable, periodic data backup.
If free pool space becomes critical, snapshots can be automatically deleted. See
“SWVR Lifeguard Service” later in this chapter. Also, snapshots are a short-term
convenience and reside on the same physical drives as the data. If something
happens to the data drives, the snapshots are also affected. Read Appendix A,
“Backup Utility Management,” for suggestions on how to back up your
TaskSmart N2400 appliance.
Page 49
2-20 Compaq TaskSmart N2400 Administration Guide
Snapshots, Restoring Files, and Directories
Snapshots may be used as a highly efficient way to maintain online backups of
a virtual disk, enabli ng immediate file an d directory recovery. Snapshots a re
assigned t o a drive letter and used exactly like virtual disks. If a file or
directory is lost or corrupted, it can be recovered easily. The user can switch to
the snaps hot drive and copy the file or directory back to its original loca tion on
the virtual disk or an alternate location.
IMPORTANT: To preserve the integrity of a point-in-time snapshot of your virtual disk,
ensure that it is exported as read-only.
Snapshots and Restoring a Virtual Disk
When data o n a virtual disk becomes corrupted, restore the virtual disk from
your normal tape backup. Alter natively, use an exi sting and valid snapshot of
the virtual disk to restore the entire virtual disk from the existing s napshot.
NOTE: Snapshots are not a replacement for normal tape backup.
CAUTION: Snapshot recovery causes temporary pool space consumption
because of the need to preallocate pool space for the newly recovered virtual
disk. There must be sufficient free pool space; otherwise, a pool-full condition
may occur and Lifeguard may delete the snapshot from which you are restoring.
If your only snapshot is deleted, you must restore from tape backup. See “SWVR
Lifeguard Service” later in this chapter.
The Restore From Snaps hot Wizard schedules the re-creation of a vir tual disk
from a snapshot. If specified, upon successful completion of the schedule, the
previous vi rtual disk and snapshot are both deleted. Perform the following
steps:
1. Remove all shares associated with the virtual disk that you are intending
to restore.
2. Delete all snapshots of the virtual disk that you are intending to recover,
except for the snapshot that will be used for the recovery. Additionally,
to free up pool space, delete any unnecessary snapshots of other virtual
disks in the same pool.
Page 50
Administrative Procedures 2-21
3. Make sure that you have enough free pool space to accomplish the
recovery, and if necessary, add logical disks to increase pool free space.
Typically, you need pool free space equivalent to the current size of the
virtual disk that you are recovering, plus the space currently used by the
snapshot that you will use for the recovery. To determine the amount of
space used by this snapshot, access the Snapshot Manager, and then
click the virtual disk listing. Locate the snapshot name in the right pane.
The amount of the space used by the snapshot is in t he Delspace
column.

Pool Sizing and Snapshots
When initially implementing snapshots, the first priority is to gain an
understanding of the amount of additional pool space required by the
snapshots. A s previously described, this assessment is a function of the write
activity, i ts localit y, the projected life time of the snapshot, and the number of
snapshots per virtual disk. By def ault, 30 percent of the pool is reserved for
snapshots
SWVR includes a Snapshot Planner utilit y. The Snapshot Planner utility must
be installed and run only on existing servers. The utility must not be run on the
TaskSmart N2400 appliance. The Snapshot Planner monitors all write activity
to a selected volume and reports the amount of pool space that a snapshot of
the volume consumes. The Snapshot Planner provides complete pool and
volume sizing information. The size of the virtual disks and the size of the
pool are equally important.
Page 55
2-26 Compaq TaskSmart N2400 Administration Guide
Snapshots and Drive Defragmentation
CAUTION: Defragmentation must not be performed when snapshots exist,
because defragmenting a virtual disk rewrites its files on the virtual disk. If you
must defragment, first delete the snapshots.
A drive defragmenter attempts to consolidate files on a drive by reading
various parts of the files and rewriting them to become contiguous on the
drive. Contiguous files increase drive performance. When virtual disks are
created from the drive space pool, the software attempts to make them as
contiguou s as possible on the underlying storage units ( logical drives and
arrays).
IMPORTANT: Defragmenting a virtual disk is appropriate when snapshots are not
present. However, the Windows 2000 operating system native defragmenter does not
work on SWVR virtual disks and must be avoided.
IMPORTANT: Drive defragmentation only operates on virtual disks formatted with a 4-KB
or smaller cluster size.

Page 58
Administrative Procedures 2-29
SWVR Lifeguard Service
SWVR Lifeguard is a utility that watches storage pools for pool-full
conditions and deletes snapshots when a po ol is nearly full. Pool-full
conditions c ause writes to the drive to be delayed. These conditions can occur
when snapshots are being used and insufficient space is left in the pool to
allow copying the data from the original virtual disk to the snapshot. If this
situation occurs, the system delays the write to both the original virtual disk
and the snapshot.
CAUTION: If the pool is improperly sized and there is an insufficient amount of
free space in the pool, Lifeguard automatically deletes the oldest snapshots.
This action prevents a critical space deficit that could delay or lose writes.
Because snapshots utilize free space in the pool, a pool-full condition can be a
result of poor or improper pool space planning. Make sure there is sufficient
space for snapshots. By default, 30 percent of the pool space is reserve d for
snapshots.
If you attempt to use a s napshot to re store your virtual disk, special ca re must
be taken to make sure there is sufficient free space in the pool. The newly
restored virtual disk is created from available free pool space. If there is
insufficient space to create the new drive, the restore will fail. However, even
if there is just enough space and other activity is occurring in the pool, the
potential for a pool-full condition exists. In this case, Lifeguard may delete the
snapshot that you are r estoring from.
CAUTION: The consequence of utilizing Lifeguard is that during a restore
Lifeguard can cause the loss of the original data represented in a snapshot. If
the amount of free space goes below a specific threshold, Lifeguard deletes one
or more snapshots to make more space available in the pool. See the
“Snapshots and Restoring a Virtual Disk” section for more information.
The SWVR Lifeguard service is installed and automatically started. The
service checks each drive letter on a system to see if it is a virtual disk or a
snapshot. If it is a snapshot, Lifeguard checks the storage pool that the drive
belongs to for its amount of current free space. This check is performed, by
default, once e ver y 10 sec on ds.
The TaskSmart N2400 appliance implementation of SWVR use s the f ollowing
default settings for the SWVR Life guard service:
■ Checks for pool-full situations onc e every 10 seconds
■ Begins deleting snapshots when the free pool space drops below the
1,024-MB threshold
Page 59
2-30 Compaq TaskSmart N2400 Administration Guide
■
Deletes the oldes t snapshot first
■ Continues t o delete up to 12 snapshots at every 10-second interval until
free pool space is above the threshold
■ Reserves 30 percent of the total pool for sna pshot use and restricts
online volume growth from causing a pool-full condi t ion by not
allowing a volume to grow into this reserved space
■ Deletes a snapshot, even if it is the only snapshot in existence
SWVR Lifeg uard posts events in the Application Event Log and can be
viewed using the Event Viewer. An event is entered for each drive that
exceeds the threshold, and additional events will be entered when a snapshot is
deleted.
NOTE: These default settings are different from those stated in the SWVR documentation
included on the TaskSmart N2400 Documentation CD.
Modify Reserved Pool Space
Although it is not recommended, you can change the percentage of free pool
space that is reserved for snapshots. If you are not using or planning to use
snapshots, removing this reserved space should not cause a problem.
CAUTION: It is possible for data corruption to occur if the percentage of free
pool space is removed and snapshots are used later without adding back the
30 percent reserved space. There is a default minimum of 1,056 MB of free
space. It is not possible to set the reserved space less than this without
activating Lifeguard service.
Increasing the percentage of free pool space poses no problem other than
reserving a larger percentage of your pool.
To modify the percentage of free pool space:
1. Click Command Prompt on t he TaskSmart N2400 console menu.
Page 60
Administrative Procedures 2-31
2. On the command line enter the command:
mfsppp nn (where nn is the percentage of free pool space to reserve)
For example:
G mfsppp 10 reserves 10 percent free pool space
G mfsppp 0 reserves 1,056 MB of free pool space (the minimum
allowed)
G mfsppp 50 reserves 50 percent free pool space
3. Type exit to exit the command line window.
For help with the mfsppp command, type mfsppp help in the command line.
Refer to the “Snapshots and Restoring a Virtual Disk” section earlier in this
chapter.
IMPORTANT: Under no circumstances should Lifeguard functionality be changed.

Managing Space Usage with Quotas
Drive quotas enable administrators to control the allocation of drive space to
individual use r s or gro u ps of user s. Whe n qu otas are enabled a nd pro pe rly
configured, it is impossible for one person or group to consume all of the
available space on a disk.
When quotas are enabled on a volume that already contains files,
Windows calculates the drive space used by all users on the volume. The quota
limit and warning level are then applied to all current users. Administrators
can then modify quotas as needed. By enabling and then disabling quotas,
administrators take advantage of the auditing capabilities provided by quotas,
without reducing server performance.
To enable dr ive quotas:
1. Log on as Admini st rator on the TaskSmart N2400 appli ance.
2. From the des kt op, do ubl e- cli ck My Comp uter.
3. In the My Computer interface, right-click on a virtual disk, and then
select Properties.
4. In the Properties window, select the Quota tab.
5. Click the Enabl e Quota Management check box, and then click OK.
NOTE: If the volume is not formatted with the NTFS file system, or if you are not a
member of the administrators group, the Quota tab is not displayed in the Properties
dialog box of the volume.
NOTE: For more information about quotas, refer to online help for
TaskSmart N2400 appliance quota help.

Windows File System Administration
Common Internet File System User and
Group Management
The Compaq TaskSmart N2400 appliance supports Network File S ystem
(NFS) and Common Internet File System (CIFS) protocols for file access over
a network. The first protocol to be discusse d is CIFS.
CIFS is the standard network file sharing mechanism used by Microsoft
Windows NT clients and servers. It is a superset of the Server Message Blocks
(SMB) network file sha ring prot ocol.
Access to CIFS shares requires a network log on, providing username and
password. A fundame nt al part of m anaging CI FS shares involves mana ging
the users and groups that have access.
There are two administration environments for users and groups:
■ Workgroup—All account information is stored locally.
■ Domain—All account informat ion is stored on a separate Window s NT
or Active Directory Domain Controller.
NOTE: The appliance is not a domain controller for other servers. If user and group
account information is locally stored, those accounts may be used only to authenticate
logons to the appliance, resulting in a workgroup configuration.
Page 63
3-2 Compaq TaskSmart N2400 Administration Guide
Domain Compared to Workgroup
TaskSmart appliances can be deployed in a workgroup environment or in a
domain environment. As previously mentio ned, CIFS is a session-based,
stateful ne t work file sharing protocol. When mapping a network drive or a
client machine, a user sends a logon credential to the server. This credential
includes the username, passwor d, and if appropriate, domain i nformation.
Using the credential, the server authenticates and provides the corresponding
access to the user. When a TaskSmart appliance is deployed into a workgroup
environment, all user and group account access permissions to file resources
are stored locally on the appliance. .
By contrast, an appliance deployed into a domain environment uses the
account database from the domain controller, with user and group accounts
stored outside the appliance. The appliance integrates with the domain
controller infrastructure
IMPORTANT: The TaskSmart N2400 appliance cannot act as a domain controller for
other systems on the network.
Managing Users and Groups Effectively
Effective user and group manage ment is dependent on how well users and
groups are organized. Administrators typically create a smal l number of
groups on t he network, and then assign users to the appropriate gr oup or
groups. File system an d share perm i s sions can be applied a t the group l evel,
rather than at the user level. Because the number of groups is small, assigning
the appropri ate permissions to all users in a select ed group, or groups, is more
efficient.
Although each organization has specific conventions, following certain
general guidelines makes administration simpler and more efficient. Because
CIFS is dependent on users and groups to grant appropriate access levels to
file shares, CIFS administration also benefit s from a consistent user and group
administration strategy.
Page 64
Windows File System Administration 3-3
Managing Usernames
It is recommended that usernames reflect a logical relationship between the
username a nd the user who uses the account. It is important that rules are
established to ensure that usernames are:
■ Systematic
■ Easy to foll ow and imple ment
■ Similar (that is, the user’s account name corresponds with the user’s
actual name )
Using a combination of the user’s first name, middle initial, and last name
results in systematic usernames for every member of a particular organization.
Common examples include:
■ First initial followed by last name (jdoe for Jo hn Doe)
■ First initial followed by middle initial and last name ( jqpublic for John
Q. Public)
■ Last name followed by first initial (DoeJ for Jane Doe)
When two users have the same initials or name, several alter natives can be
used to create unique names. For example, a number can be added to the end
of the userna me (jdoe1 and jdoe2). You can also apply systematic naming
rules (jdoe=John Doe and doej=Jane Doe).
Other conventions can be applied. Just ensure that conventions are bo th
systematic and consistent.

Domain Environment
Administering users and groups in a domain environment i s similar in a
mechanical sense to administering them in a workgroup environment. If using
an Active Directory domain co nt roller, t he Computer Management tool allows
for adding, modifying, and removing users in the same MMC context as in a
workgroup environm ent. The concepts, however, are very dif ferent.
When in a domain environment, the server is a member of the domain. The
domain controller is a repository of accounts and account access for the
appliance. Client machines are also members of the domain, and users log on
to the domain through their Windows clients. The domain controller also
administers user accounts and appropriate access levels to resources that are a
part of the domain. Additional information about planning for domain
environments can be found at the Compaq ActiveAnswers™ website in the
eBusiness Infrastructure solutions area:
http://www.compaq.com/ActiveAnswers/
The configurations of the domain controller or controllers are reflected on the
TaskSmart N2400 appliance, because it obtains user account information from
the domai n controlle r or controllers whe n deployed in a domain enviro nment.
The appliance cannot act as a domain controller itself.
IMPORTANT: The domain administration tasks described, whether for an Active Directory
domain or a Windows NT 4.0 domain, are tasks that configure the domain controller or
controllers, and not the TaskSmart N2400 appliance.
Active Directory Domain—Administering Users
and Groups
The process of adding, removing, or modifying users and groups i n an Active
Directory domain environment is similar to that for administering users and
groups in a workgroup environment. There are three es sential differences:
■ Users and groups are administered on the Active Directory domain
controller rather than on the appliance.
■ Computer accounts must be administered in t he domain as well as user
and group accounts.
■ A different tool is used to manage domain accounts.
Page 77
3-16 Compaq TaskSmart N2400 Administration Guide
You administer user, group, and computer accounts in an Active Directory
domain environment using one of two methods:
■ From the Active Directory domain controller console, not the
TaskSmart N2400 appliance
On the taskbar, select Start, Programs, Administrative T ools, and
then Active Directory Users and Computers. This selection lau nches
an MMC that allows for the administration of user, group, and computer
accounts in the domain.
■ Remotely from a client machine that points to the Active Directory
domain cont roller
1. Log on using a Windows 2000 client as a domain administrator.
IMPORTANT: The administrator must have sufficient access rights to administer users
and groups on the domain.
2. Choose Start, and then Run.
3. Type MMC.EXE in t he dialog box.
4. Select Console, and then Add/Remo ve Snap-in.
5. Click Add. The Add Standalone Snap-in dialog box is di splayed, as
shown in Figure 3-9.
Page 78
Windows File System Administration 3-17
Figure 3-9. Add Standalone Snap-in dialog box
6. With the Active Directory Users and Computers snap-in selection
highlighted, click Add.
Page 79
3-18 Compaq TaskSmart N2400 Administration Guide
7. Afte r the snap-in is added, you must connect to the appropr iate domain
to enable remote administration. To do this:
a. Select the Active Directory Users and Computers snap-in.
b. Click Action, and then Connect to Domain.
c. A dialog box a sks you to enter the domain nam e of the Act i ve
Directory to be administered.
d. Enter the dom ai n na me .
NOTE: Full name resolution must be properly configured in the network environment in
which the domain resides. Be sure that DNS, hosts/LMHOSTS files, or both are properly
set up.
NOTE: Users with sufficient permission to administer the domain must be logged on to
the client machine. Typically, such users are members of the domain administrators
group, but other groups can also have administrative permissions.

Windows File System Administration 3-19
Active Directory Domain—Adding the
TaskSmart N2400 Appliance
After you have properly made the connections to yo ur domain t hrough the
Active Directory Users and Computers snap-in, you can begin administering
this portion of the Active Directory. The first task is to add the
TaskSmart N2400 appliance to the Active Directory by following these steps:
1. Select the Computers folder in the snap-in.
2. Choose Action, New, Computer. This process launche s the New
Object - Computer di alog box, pi ctured in Figure 3-10.
Figure 3-10. New Object - Computer dialog box
Page 81
3-20 Compaq TaskSmart N2400 Administration Guide
3. Enter the appropriate computer name in the first field.
NOTE: The Computer name (pre-Windows 2000) field automatically populates. The Allow
pre-Windows 2000 computers to use this account check box option is not relevant and
must remain unchecked, because the appliances are based on Windows 2000.
4. If necessary, click Change to c hange the default group for the computer
account; however, remember that the computer account (not the user
accounts) accesses the Active Directory through the computer.
5. Select OK.
Page 82
Windows File System Administration 3-21
Active Directory Domain—Creating User and
Group Accounts
To create use r and gro up accounts on the Active Directory console , you can
use the same Active Directory Users and Computers snap-in used in the
“Active Directory Domain—Ad di ng the TaskSmart N2400 Appliance ” section
earlier in this chapter. Instead of using the Computers folder of the sna p-in,
however, use the Builtin folder and the Users folder.
For help, sele ct the appropriate MMC snap-in, and the n click Help from the
Console menu. Documentation for planning and de ploying the A ctive
Directory can be obtained at the Compaq ActiveAnswers website in the
eBusiness Infrastructure solutions area:
http://www.compaq.com/ActiveAnswers/
Active Directory—Builtin Folder
The Builtin folder contains information about all the groups added to a default
Active Directory. Default Active Directory folders contain the following
groups:
■ Account Operators
■ Administrators
■ Backup Operators
■ Guests
■ Pre-Windows 2000 Compatible Access
■ Print Operators
■ Replicator
■ Server Operators
■ Users
NOTE: References to users and groups are presented in the context of the Users group,
except when demonstrating how to create a new group.

Active Directory—Creating a New User
The Users folder is the repository for displaying all t he users and groups on the
Active Directory and is useful when modifying the properties of a particular
user or group. One of the basic functions of the U s ers folder is the ability to
add users and groups.
1. Highlight the Users folder in the Active Directory Users and Computers
snap-in.
2. Select Action, New, User. The New Object - User dialog box shown in
Figure 3-11 is displayed.
Figure 3-11. New Object - User dialog box, user information
Page 84
Windows File System Administration 3-23
3. Enter the information into the text boxes.
NOTE: The logon context is USER@DOMAIN in the Active Directory, but the legacy logon
context of DOMAIN\USER is supported.
After entering data in the First name, Initials, and Last name fields, the
Full name value automatically generates. When entering the User logon
name, the pre-Windows 2000 User logon name f ills in aut omatically. It
is advisable to accept the default entry, particularly if there are older
machines included on the network infrastructure.
NOTE: If multiple domain controllers are used, Active Directory or otherwise, it is
recommended that user account names be unique across domains. Unique naming
makes NFS administration easier.
4. When the required information is en ter ed, initial user values have been
set. Click Next and the dialog box depicted in Figure 3-12 is displayed.
Figure 3-12. New Object - User dialog box, password information
5. Enter the password information.

6. Click the appropriate check boxes. The check boxes are identical to the
ones that are displayed when you create a new user in a workgroup
environment, except that these user properties are stored in the Active
Directory rather than locally on the appliance.
NOTE: In this environment, it is acceptable to force the user to change a password at the
next logon. Users who need to access CIFS file resources on an appliance deployed in an
Active Directory environment log on to the Active Directory from their remote
workstations. The Active Directory appropriately forces remote users to change
passwords to ensure security.

Windows File System Administration 3-33
Modifying a User—Member Of Tab
The Member Of tab lists the groups that apply to a particular user. The
member information is important because CIFS is a stated protocol that uses
user and group authentication to provide or restrict access to file resources.
Placing a user strategically into one or more groups means that the
administrator can provide or restrict access by group rather than by user.
Because there are usually more users than groups, effective placement of users
into groups is critical to efficient share management.
Figure 3-17. Modify User Properties - Member Of tab dialog box
Page 95
3-34 Compaq TaskSmart N2400 Administration Guide
The Primary Group section of the dialog box r efers to the fi rst group that the
user is associated with when applications request user informatio n. S ome
POSIX-com pl iant appl i cations differentiat e between the primar y group and
other member groups when deciding on group contexts within which to run an
application. It is usually unnecessary to change primary group member
information in a CIFS file-serving environment. It can be useful, however, to
change member information when using the Active Directory to control access
to servers other than a TaskSmart N2400 appliance server.
Modifying a User—Sessions Tab
The Sessions tab allows the administrator to set pr operties that instruct the
Active Directory how to manage client sessions that are disconnected or timed
out. Because the CIFS protocol is session based, the manner in which
disconnected sessions are handled can affect the way clients interact with a
TaskSmart N2400 appliance. The dia log box in Figure 3-18 illustrates how
sessions information is enter ed.
Page 96
Windows File System Administration 3-35
Figure 3-18. Modify User Properties - Sessions tab dialog box
By default, disconnected sessio ns are not ended, even if the client-server
connection is accidentally broken, as in the case of a faulty network cable. The
default also allows any client on the network to reconnect to a disconnected
session. Potential security ramifications can affect file-serving functions and
the integrity of the data on an appliance. For detailed security information,
refer to the Microsof t Active Directory Documentation included with
Windows NT.
