What is the access terminal?

The L-series access terminals enable you to dramatically cut computing costs by sharing the untapped power of PCs. The access terminals, Ethernet-based extension protocol, and terminal services software work together to efficiently harness excess computing capacity and enable multiple users to share a single PC. Best of all, IT staff and end users do not need special training because this end-to-end solution is easy to manage and is compatible with standard PC applications.

What is the terminal services softwar e?

Note: This document uses the following terms interchangeably: "User software," "host PC software," "terminal services software," and "NCT-2000-XP".

NCT-2000-XP, the terminal services software, divides the host PC's resources into independent sessions that give each user their own robust PC experience. One PC can support up to ten users when running on a desktop operating system, such as Microsoft Windows XP. With a server operating system on the host (Microsoft Windows 2003 Server or Linux), up to 30 users can be supported simultaneously. NComputing terminal service software also works with the optional NControl and NShield software that add more centralized management capabilities such as remote monitoring and host PC data backup.

Features

The L-series access terminals do not have a CPU, hard drive or CD-ROM, yet most users find it indistinguishable from a full PC environment. The L-series exclusive technolog y allows you to add up to 30 computing terminals to your existing PC. Each access terminal offers a full and independent computing experience.

Simultaneous desktop operation

Each access terminal accesses the host PC OS and can run its applications concurrently and independently through Ethernet.

Minimal Maintenance Required

You only have to maintain and upgrade the host PC since the access terminals have no CPU, hard drive, or CDROM.

Small sleek design

Allows more room in your office or on your desk, and can even mount on the back of your LCD with included bracket.

Eco-friendly

Since the access terminals have no moving parts, it makes no noise and saves energy by drawing only 5 watts.

Supports multiple resolutions

640x480, 800x600, 1024x768 and 1280x1024, by 16-bit colors.

Additionally, the L130 supports 1440x900 by 16-bit colors and the L230 supports 1440x900 by 24-bit colors.

New Feature: Microphone

The L230 now includes a microphone port.

Minimum System Requirements

A host PC with at least:

• A 2 GHz processor

• 512 MB RAM

• 60 GB hard disk drive

• Ethernet switch or router

Do not use a notebook PC as the host. Notebooks use power-saving features and different technologies than a typical desktop PC, and this causes power management and memory problems.

Conceptual Diagram

Installation

Install the terminal services software (optional, but must be done once)

Information & Settings

The "Product Information" tree item shows information about the installed terminal services software.

The "Licensee information" tree item shows the information entered during the registration process.

The "System Settings" tree item shows the following settings for the terminal services software. Double-clicking on the name of the setting allows you to adjust it (unless it is read-only, which is specified below).

• Maximum number of stations (incl. Host): Displays the maximum number of sessions the terminal

services software is configured to support. This number includes the host PC. This setting is read-only.

• Current number of sessions: Displays the number of active sessions. This setting is read-only.

• This machine: Displays the name of the host PC. This setting is read-only.

• This user: Displays the currently logged-in user’s username. This setting is read-only.

• System uptime: Displays how long the host computer has been logged on. This setting is read-only.

• Main Station AutoLogon: Displays whether or not the host PC is set to automatically logon at boot-up.

• Delay until shutdown (seconds): Displays the default amount of time after a shutdown command is

issued on the host until the shutdown occurs. After the shutdown command is issued on the host, the shutdown timer starts. Then, a window pops up on each terminal session that tells the users they must logoff since the host is shutting down. Each user must save their work. Also, a window pops up on the host that enables the administrator to abort the shutdown timer and start the shutdown immediately, or cancel the shutdown. When the shutdown timer expires, the shutdown occurs.

• Disable Send Broadcast Message: Displays whether or not the administrator has disabled broadcast

messages. See the description of the “Sessions” tree item for more information about how broadcast messages work.

• Prevent access of the USB-storage devices to the attached terminal field: Displays whether or not the

administrator has globally prevented access to USB devices on access terminals.

• Remote View/Control allowed: Displays whether or not the administrator has configured the terminal

services software to allow administrators to remotely view user and control user sessions.

• Clean up disconnected sessions not in use: Displays whether the terminal services software

automatically looks for disconnected sessions that are not in use and logs them out after a defined period of time. If this feature is turned off (set to “No” or “0”), when any terminal drops its connection, the connection remains active on the host. When the user reconnects, their disconnected session is reconnected to their new session and all their open files and applications are available again. Also, in this case, the only way to end a disconnected session is for an administrator to stop the session from the console software. If this feature is turned on (set to any whole number up to 999), the same behavior applies, but when a session is disconnected, a timer starts. If the user reconnects before the timer is up, their disconnected session is reconnected to their new session and all their open files and applications are available again. If the timer runs out and the session is still disconnected, the terminal services software will end the session by itself. This makes sure that disconnected sessions do not reserve resources for an indefinite period. By default, this is set to “No.”

• Support WTSAPI32 Interface: Displays whether or not the terminal services software has turned on

support for the Windows Terminal Services Application Programming Interface, or WTSAPI32. At times, this setting is required for certain applications to behave properly.

• Disable background-bitmaps under Windows XP: Displays whether or not the u ser is able to set their

own background bitmap for their Windows XP desktop.

• Do not display last user name: Displays whether or not the terminal services software displays the last

user name that logged on using a particular terminal. This is sometimes enabled as a security measure.

• UTMA/UTSA USB port support: Displays whether the administrator has set the terminal ser vices

software to allow using the USB port on L200 and L230 access terminals.

• Administrator Password: Displays whether an administrator password is set.

• Autologon on the Host Station: Displays whether the host PC is set t o bo ot up without the Windows

logon screen of the host PC.

The "Serial Numbers" item shows a list of serial numbers of terminals that have connected to the terminal services software. For each serial number, it shows the number of licenses required for that terminal, the station number (if available), whether or not it is registered, and a description of the device.

USB-Device Assignment(s)

Note: This feature is only available on the L200 and L230.

In the "USB-Device Assignment(s)" tree item, you can control connections between USB ports on the host and terminal sessions. To use this function, navigate the tree to select a USB port. When you right-click on an entry under “USB-Device Assignment(s)”, you can de-select the “Hide the ports that are not connected” item to see all ports. After selecting a port, the following information is displayed:

• The port number.

• If a device is connected, the device's simple name.

• The device's longer name, usually including the manufacturer and model.

• A check box for "Allow all users access to every USB port". When this is selected, all USB ports are

connected, as if in one hub. When it is not checked, there is a list of USB ports where you select which ones to be connected to the selected device. In the list, there is each terminal's MAC address and serial number along with a checkbox.

When you click on the "Apply" button, changes to the USB-Device assignments are saved. To discard changes, simply navigate to another tree item or close the console without clicking on the "Apply" button.

Software Settings (LAN)

The "Software Settings (LAN)" tree allows you to see and change settings for the host PC and all other PCs on the network that are running the terminal services software. Once you select a server in the tree, the same settings are present as are in the "Software Settings (local)" tree item.

Hardware Settings (LAN/local)

The "Hardware Settings (LAN/local)" tree allows you to see and change settings for all access terminals on the network.

When you select the "UTMA/UTSA Devices" tree item, there is a table in the right side of the window that contains information about each access terminal. There is a very wide variety of information available for each terminal. Clicking on the "Columns" button enables you to select what columns are displayed. You can select a preconfigured group of columns or you can click on the "Advanced" button to select individual columns to display.

Double-clicking on an entry in the table brings up the "Device Properties" window that shows a list of properties and buttons for changing the device's settings.

The settings you can change are all the same settings you can change when you use the "Options" window on the access terminal itself. See the access terminal setup section for details on these settings.

Note: There are four settings you can change in the "Device Properties" window that you can't change in the access terminal's "Options" window. One is the device's name. You can configure it on the management console by clicking on the "Connection Settings" button. The second is the access terminal's group membership. You can add the access terminal to a group or multiple groups by clicking the "Member of Groups" button and adding the groups to the list. The third is enabling and disabling USB on the selected device. In the "Device Properties" window, there is a checkbox labeled, "Enable USB on this device". The fourth is the “Auto-Connect” feature. It is available under the “Connection Settings” button in device configuration. This feature enables configuring the access terminal to automatically connect using a specific profile when it is restarted or logged off.

You can print the access terminal's information by clicking on the "Print" button. In the "UTMA/UTSA Device Group(s)" tree item, you can create groups of access terminals for administrative

purposes. You can use groups to organize your access terminal records by any criteria. Access terminals can belong to as many groups as necessary.

Right-clicking on the "UTMA/UTSA Device Group(s)" tree item will bring up a context menu where you can create a group.

In the “Enter UTMA Device group name” window, enter the group name and description.

Troubleshooting error messages

Error messages on the access terminal DHCP server was not found

If the access terminal cannot find a DHCP server, this error message appears.

Make sure there is a DHCP server on the current network. Make sure a LAN cable is connected to the access terminal. Make sure the LAN cable connected to the access terminal is not a cross-over cable. Make sure the LAN cable is properly connected to the networking equipment. If there is no DHCP server on the current network, change to using a static IP address. See the section on

installing the access terminal for instruc tions.

No Terminal Server found or not all services initialized yet, please click on the connection list and try it again

This occurs when the access terminal is set to find the host PC and it does not find the host PC where the terminal services software is installed.

Make sure the NCT-2000-XP program is installed on the host computer. Make sure the LAN cable is properly connected to the host computer. Make sure the host computer and access terminal are in the same local area network. Make sure any firewall or anti-virus programs installed in the host computer or network equipment are

compatible with the terminal services so ftw a re.

Host unreachable…

When the access terminal cannot connect to the host PC, this message appears. Make sure the server connection list is configured correctly. See the section about configuring the

access terminal. Make sure the terminal services software is in sta lle d on t he hos t PC. Make sure the host computer and access terminal are in the same network.

Make sure any firewall or anti-virus programs installed in the host computer or network equipment are compatible with the terminal services so ftw a re.

TS ERROR – INVALID OR NO SERIA L NUM BE R!

This message appears when no serial number exists in the host computer. This message does not indicate an error regarding the serial number of the access terminal.

Please see the section about product registration to register the terminal services software and the access terminals.

Connection was closed but your data is not lost and application is still running on the server. Please connect to the terminal server later.

This message appears when the connection stops due to abnormalities occurring on the host PC or network equipment.

Check the Host PC or the network equipment when this message appears and restart the Host PC and access terminal. Unless the Host PC is rebooted, existing data in the Host PC may be used as is.

Check to see if the host PC is overloaded. Check to see if the network traffic is overloaded. Check to see if the host PC is unstable. There is a feature in the terminal services software that keeps disconnected sessions running and available. If the

user reconnects while a disconnected session for that username is present, the software will connect the disconnected session to the new session. The user will see the desktop as it was when the disco nnection occurred .

The administrator can configure the software to keep disconnected sessions running and available indefinitely or to close them automatically after being disconnected for a specified period o f time. The setting is in the administrative console’s system settings and is called, “Clean up disconnected sessions not in u se.”

Authorization error

When two access terminals use the same serial number simultaneously, the error message appears. Check all serial numbers in the terminal services software console.

TS ERROR – Stations Limit Exceeded !

When an access terminal attempts to connect to the host PC and the number of allowed connections is exceeded, this message appears.

Check how many access terminals are connected to the host PC. Check what operating system is installed on the host PC.

Troubleshooting error messages on the Host PC

Multi user Error

Microsoft distributes Windows updates, and some security updates may conflict with the terminal services software. A conflict may display an error message or disable the access terminal. If this happens, a new version will be distributed very quickly through the automatic software update feature.

Glossary

• Access terminal: a network computing terminal using NComputing patent technology. It doesn't use

CPU, VGA, and main chipsets, only use a programmable SoC to connect to Host PC. A terminal using UTMA technology can be connected to Host PC by using the LAN cable. Also, it can be connected to remote PC through Internet using TCP/IP.

• Administrator: a person who is responsible for managing a multi-user computing environment, such as a

local area network (LAN). The responsibilit ies of the system administrator typically include: installing and configuring system hardware and software; establishing and managing user accounts; upgrading software; and backup and recovery tasks.

• Alias: a fictitious name

used by an individual as an alternative to her or his true name.

• Client/Server: describes the relationship between two computer programs in which one program, the

client, makes a service request from another program, the server, which fulfills the request.

• Console: the text entry and display device for system administration messages, particularly those from

the BIOS

or boot loader, the kernel, the init system and the system logger.

• DHCP: (Dynamic Host Configuration Protocol) is a communications protocol that lets network

administrators centrally manage and automate the assignment of Internet Protocol (IP) addresses in an organization's network. Without DHCP, the IP address must be entered manually at each computer in an organization and a new IP address must be entered each time a computer moves to a new location on the network.

• Download: the transmission of a file from one computer system to another.

• Ethernet: the most widely-installed local area network (LAN) technology - specified in a standard, IEEE

802.3.

• Firewall: a set of related programs (located at a network gateway server) that protect the resources of a

private network from users on other networks and control what outside resources its own users have access to. (The term also implies the security policy that is used with the programs.)

• Gateway: a network point that acts as an entrance to another network. On the Internet, a node or

stopping point can be either a gateway node or a host (end-point) node.

• Host Computer: a computer in which the NCT-2000-XP program has been installed

• Internet: a worldwide system of computer networks in which users at any one computer can, if they have

permission, get information from any other computer (and sometimes talk directly to users at other computers).

• IP Address: the Internet Protocol (IP

) is basically the set of rules for one network communicating with any other (or occasionally, for broadcast messages, all other networks). Each network must know its own address on the Internet and that of any other networks with which it communicates. To be part of the Internet, an organization needs an Internet network number, which it can request from the Network Information Center (NIC). This unique network number is included in any packet sent out of the network onto the Internet.

• LAN: local area network (LAN) is a group of computers and associated devices that share a common

communications line or wireless link and typically share the resources of a single processor or server within a small geographic area (for example, within an office building). Usually, the server has applications and data storage that are shared in common by multiple computer users. A local area network may serve as few as two or three users (for example, in a home network) or as many as thousands of users (for example, in an FDDI network).

• Log on: in general computer usage, logon is the procedure used to get access to an operating syste m or

application. Almost always, a logon requires that the user have (1) a user ID and (2) a password. Often, the user ID must conform to a limited length such as eight characters and the password must contain at least one digit and not match a natural language word

• MAC Address: in a LAN or other network, the MAC (Media Access Control) address is your computer' s

unique hardware number. (On an Ethernet LAN, it's the same as your Ethernet address.) When you're connected to the Internet from your computer, a correspondence table relates your IP address to your computer's physical (MAC) address on the LAN.

• NCT-2000-XP: NComputing terminal services software for Windows 2000 and XP

• PC: Personal Computer

• Router: in packet-switched networks such as the Internet, a router is a device or, in some cases, software

in a computer, that determines the next network point to which a packet should be forwarded toward its destination. The router is connected to at least two networks and decides which way to send each information packet based on its current understanding of the state of the networks it is connected to.

• User: one who uses a computer system. Users may need to identify themselves for the purposes of

accounting, security, logging and resource management. In order to identify oneself, a user has an account and a username.

• USB: (Universal Serial Bus) is a standard designed to allow peripherals to be connected to a computer

using a standardized interface socket and to improve plug-and-play

capabilities by allowing devices to

be connected and disconnected without rebooting

the computer.

• UTMA: Ultr a Thin Multi Access

FAQ

Q: Must the versions of the terminal services software in a network be the same?

A: Yes, since different versions m i ght cause data communication problems. Please keep all termina l services software updated with the latest version.

Q: When I start my access terminal, why is the server connection list blank? I have the NCT2000-XP software on a host PC in my network. I can connect to the host PC if I provision its IP address in the access terminal.

A: This condition occurs when the host and access terminals are on independent subnets. The access terminal can run in this mode, but will ne ver s e e the host PC in its server connection list.

Q: When I go to the device list in the administration console, why do some of my access terminals never show up in the list?

A: This condition occurs when the host and access terminals are on independent subnets. The access terminal can run in this mode, but its record will never appear in the administration console’s device list.

Q: When I try to do a manual firmware update on the access terminal, why does it not connect to the host PC and download the firmware?
