How Do I Log In? 2
Before you can log in and connect to a remote desktop or application, a system administrator at your
company must set up your user account. If your system administrator has not set up your user account, you
cannot use Horizon Client or HTML Access.
If Horizon Client prompts you for a server name and domain name, your system administrator must tell
you the server name to type and domain to select. At some companies, Horizon Client automatically
connects to the correct server and selects the correct domain for you.
If you do not know your user name or password or how to reset your password, contact the system
administrator at your company.
When you are ready to log in and get started, see “Connect to a Remote Desktop or Application,” on
page 9.

Connecting to Remote Desktops and
Applications 3
You can use Horizon Client to connect to remote desktops and applications.
This chapter includes the following topics:
“Connect to a Remote Desktop or Application,” on page 9
n
“Trust a Self-Signed Root Certicate,” on page 10
n
“Use Unauthenticated Access to Connect to Remote Applications,” on page 11
n
“Log O or Disconnect,” on page 12
n
Connect to a Remote Desktop or Application
Use your Active Directory credentials to connect to the remote desktops and applications that you are
authorized to use.
Prerequisites
Obtain login credentials, such as an Active Directory user name and password, RSA SecurID user name
n
and passcode, or RADIUS authentication user name and passcode.
Obtain the NETBIOS domain name for logging in. For example, you might use mycompany rather than
n
mycompany.com.
Procedure
1 In the Login dialog box, if you are prompted for RSA SecurID credentials or RADIUS authentication
credentials, enter the user name and passcode, and click Login.
The passcode might include both a PIN and the generated number on the token.
2 If you are prompted a second time for RSA SecurID credentials or RADIUS authentication credentials,
enter the next generated number on the token.
Do not enter your PIN and do not enter the same generated number entered previously. If necessary,
wait until a new number is generated.
If this step is required, it is required only when you mistype the rst passcode or when conguration
seings in the RSA server change.
VMware, Inc.

Page 10
VMware Horizon HTML Access User Guide
3 In the Login dialog box, enter your login credentials.
a In the Username text box, enter your valid Active Directory user name in either username,
domain\username, or username@domain format.
If the Domain text box is disabled, you must use either the domain\username or username@domain
format.
b Enter your password.
c (Optional) If the Domain text box is enabled, select a domain name, if it is not already correctly
populated.
N To cancel the login process, click Cancel before the login process nishes.
4 (Optional) On the desktop and application selection screen, before you select the item you want to
access, to mark a remote desktop or application as a favorite, click the gray star inside the icon for the
desktop or application.
The star icon turns from gray to yellow. The next time you log in, you can click the star icon in the
upper-right part of the browser window to display only favorites.
5 Click the icon for the remote desktop or application that you want to access.
The remote desktop or application is displayed in your browser. A navigation sidebar is also available.
You can click the tab at the left side of the browser window to display the sidebar. You can use the
sidebar to access other remote desktops or applications, display the Seings window, copy and paste
text, and more.
What to do next
If, soon after connecting to a desktop or application, you get disconnected and see a prompt asking you to
click a link to accept the security certicate, you can select whether to trust the certicate. See “Trust a Self-
Signed Root Certicate,” on page 10.
Trust a Self-Signed Root Certificate
In some cases, when connecting to a remote desktop or application for the rst time, you might be prompted
by the browser to accept the self-signed certicate used by the remote machine. You must trust the certicate
before the connection can be made to the remote desktop or application.
Most browsers will give you the option to permanently trust the self-signed certicate. If you do not choose
to permanently trust the certicate, you must verify the certicate every time you restart your browser. If
you are using a Safari browser, you must permanently trust the security certicate in order to establish the
connection.
Procedure
1 If your browser presents an untrusted certicate warning or a warning that your connection is not
private, examine the certicate to verify that it matches the certicate that is used by your company.
You might need to contact your Horizon administrator for assistance. For example, in a Chrome
browser, you might use the following procedure.
a Click the lock icon in the address bar.
b Click the information link.
c Verify that the certicate matches the certicate that is used by your company.
You might need to contact your Horizon administrator for assistance.
10 VMware, Inc.
Page 11
Chapter 3 Connecting to Remote Desktops and Applications
2 Accept the security certicate.
Each browser has its own browser-specic prompts for accepting or always trusting a certicate. For
example, in a Chrome browser, you can click the Advanced link on the browser page, and click Proceed
to server-name (unsafe).
In a Safari browser, use the following procedure to permanently trust the certicate.
a Click the Show buon when the untrusted certicate dialog box appears.
b Select the Always Trust check box and click Continue.
c When prompted, provide your password and click Update .
The remote desktop or application is launched.
Use Unauthenticated Access to Connect to Remote Applications
A Horizon administrator can use the Unauthenticated Access feature to create Unauthenticated Access users
and entitle those users to remote applications on a Connection Server instance. Unauthenticated Access
users can log in to the server anonymously to connect to their remote applications.
Prerequisites
Obtain the following information from your Horizon administrator:
Server name to use for connecting to the server.
n
An Unauthenticated Access user account to use for logging in anonymously.
n
Procedure
1 Open a browser. Use one of the following URI syntaxes to connect to the Connection Server instance on
which you have unauthenticated access to remote applications.
hps://authority-part?unauthenticatedAccessEnabled=true
n
hps://authority-part?
n
unauthenticatedAccessEnabled=true&unauthenticatedAccessAccount=anonymous_account
In the above URI syntaxes, the authority-part species the server address and, optionally, a non-default
port number. Server names must conform to a DNS syntax. To specify a port number, use the following
syntax: server-address:port-number . The anonymous_account is the Unauthenticated Access user account
created for logging in anonymously.
Connections to Connection Server always use SSL. The default port for SSL connections is 443. If
Connection Server is not congured to use the default port, use the format shown in this example:
horizon.company.com:1443.
2
(Optional) If you did not specify the unauthenticatedAccessAccount query, select an
Unauthenticated Access user account from the User account drop-down menu, if necessary, and click
Submit.
If only one Unauthenticated Access user account is available, the user account is selected by default.
The application selection window appears.

H.264 Decoding
If you use a Chrome browser, you can allow H.264 decoding in the HTML Access client for remote desktop
and application sessions.
When you allow H.264 decoding, the HTML Access client uses H.264 decoding if the agent supports H.264
encoding. If the agent does not support H.264 encoding, the HTML Access client uses JPEG/PNG decoding.
If you are connected to a remote desktop or application, you can allow H.264 decoding by turning on the
Allow H.264 decoding option in the Seings window, which is available from the sidebar. You must
disconnect and reconnect to the remote desktop or application for the new seing to take eect.
If you are not connected to a remote desktop or application, you can click the toolbar buon in the
upper-right corner of the desktop and application selector screen and turn on the Allow H.264 decoding
option in the Seings window. The new seing takes eect for any sessions that are connected after you
change the seing.
Setting the Time Zone
The time zone used in a remote desktop or application is automatically set to the time zone in your local
system. However, when using the HTML Access client, if the time zone cannot be correctly determined due
to certain daylight saving policies, you might need to set the time zone manually.
To manually set the correct time zone information to use before you connect to a remote desktop or
application, click the toolbar buon in the upper-right corner of the desktop and application
selector screen. Turn o the Set Time Zone Automatically option in the Seings window and select one of
the time zones from the drop-down menu.
The value you selected is saved as your preferred time zone to use when connecting to a remote desktop or
application.
16 VMware, Inc.
Page 17
If you are already connected to a remote desktop or application, return to the desktop and application
selector screen to change the current time zone seing.
The Set Time Zone Automatically option is not available from the Seings window that is accessible from
the sidebar.
N When using the Chrome browser on an Android system, if the Set Time Zone Automatically option
is set to true and you change the Android system's time zone, the new time zone is not automatically
synchronized with the remote desktop. This is a Chrome limitation on the Android system. You must restart
the Android and the Chrome browser to synchronize the selected time zone.
Using the Sidebar
After you connect to a remote desktop or hosted application, you can use the sidebar to launch other
applications and desktops, switch between running desktops and applications, and perform other actions.
When you access a remote application or desktop, the sidebar appears on the left side of the screen. Click the
sidebar tab to display or hide the sidebar. You can also slide the tab up and down.

Transferring Files Between the Client and a Remote Desktop
With the le transfer feature, you can transfer (upload and download) les between the client and a remote
desktop. File transfer to or from applications is not supported.
The Horizon administrator can congure the ability to allow, disallow, or allow in one direction only, the
transfer of les. The default is upload only.
VMware, Inc. 21
Page 22
VMware Horizon HTML Access User Guide
You can download a le up to 500 MB in size, and upload a le up to 2 GB in size. For 32-bit Internet
Explorer 11, downloading a le larger than 300 MB might not work. To resolve the issue, run Internet
Explorer 11 in 64-bit mode.
You cannot download or upload folders, or les that have a size of zero.
Safari on iOS and Safari 8 do not support upload or download. Safari 9 or later do not support download.
If le transfer is in progress in a desktop session and the user opens a connection to a second desktop, and if
a security warning is displayed (this can happen if no valid certicate was installed, for example), ignoring
the warning and continuing to connect to the second desktop will cause the le transfer in the rst desktop
session to abort. This is expected behavior.
N The ability to download is aected by the group policy seing for clipboard redirection. If clipboard
redirection is disabled from the server to the client, then le download is also disabled.
Download Files from a Desktop to the Client
With Horizon Client you can download les from a remote desktop to the client machine.
Procedure
1 Click the le transfer icon at the top of the sidebar.
The Transfer Files window opens.
2 Click Download.
3 Select one or more les on the remote desktop.
4 Press Ctrl+c to start the download.
5 After the download is complete, click the download icon to save the les on the client machine.
Upload Files from the Client to a Desktop
With Horizon Client you can upload les from the client machine to a remote desktop.
Procedure
1 Click the le transfer icon at the top of the sidebar.
The Transfer Files window opens.
2 Click Upload.
3 Drag and drop les into the Transfer Files window or click Choose Files to select les.
The selected les are uploaded to the My Documents folder.
With Internet Explorer 11 and Chrome on ChromeBook, if you drag and drop folders, les of zero size,
or les larger than 2 GB, you get an error message as expected. After you dismiss the error message,
you can no longer drag and drop les that can be transferred.
Using DPI Synchronization
The DPI Synchronization feature ensures that the remote desktop's DPI seing matches the client machine's
DPI seing for new remote sessions. When you start a new session, Horizon Agent sets the DPI value in the
remote desktop to match the DPI value of the client machine.
The DPI Synchronization feature cannot change the DPI seing for active remote sessions. If you reconnect
to an existing remote session, the Display Scaling feature scales the remote desktop or application
appropriately.
22 VMware, Inc.
Page 23
Chapter 4 Using Remote Desktops and Applications
The DPI Synchronization feature is enabled when the High Resolution Mode seing is disabled in the
Seings window. Beginning with HTML Access version 4.5, if an administrator disables the Horizon Agent
DPI Synchronization group policy seing, the DPI Synchronization feature can be disabled, but the Display
Scaling feature cannot be disabled. You must log out and log in again to make any conguration changes
take eect. For more information, see the Conguring Remote Desktop Features in Horizon 7 document.
The DPI Synchronization feature requires Windows 7 or later for single-session desktops, Windows Server
2008 R2 or later for published desktops and applications on RDS hosts, Horizon Agent 7.0.2 or later, and
HTML Access version 4.4 or later.
Following are tips for using the DPI Synchronization feature:
If you change the DPI seing on the client machine, you must log out and log in again to make
n
Horizon Client aware of the new DPI seing on the client machine. This requirement applies even if the
client machine is running Windows 10.
If you start a remote session on a client machine that has a DPI seing of more than 100 percent, and
n
then use the same session on another client machine that has a dierent DPI seing of more than 100
percent, you must log out and log back in to the session on the second client machine to make DPI
synchronization work on the second client machine.
Although Windows 10 and Windows 8.x machines support dierent DPI seings on dierent monitors,
n
the DPI Synchronization feature uses the DPI value that is set on the client machine's monitor in which
the Web browser used for launching the HTML Access client session is located. HTML Access does not
support dierent DPI seings in dierent monitors.
If you want to sync up with another monitor with a dierent DPI seing, you must log out of the
n
remote desktop or application, drag the Web browser used for launching the HTML Access client
session to the other monitor, and log back in to the remote desktop or application to make the DPI
seings match between the client system and remote desktop or application.

Screen Resolution
If the Horizon Administrator congures a remote desktop with the correct amount of video RAM, the Web
client can resize a remote desktop to match the size of the browser window. The default conguration is
36MB of video RAM, which is comfortably more than minimum requirement of 16MB if you are not using
3D applications.
If you use a browser or Chrome device that has a high pixel density resolution, such as a Macbook with
Retina Display or a Google Chromebook Pixel, you can set the remote desktop or application to use that
resolution. Turn on the High Resolution Mode option in the Seings window, which is available from the
sidebar. (This option only appears in the Seings window if you are using a high-resolution display or a
normal display that uses a scale that is greater than 100 percent.)
Use Multiple Monitors
By using a Chrome browser (version 55 or later), you can use multiple monitors in HTML Access Web client
to display a remote desktop window.
You can add up to one additional monitor to your primary monitor to display the current remote desktop
window to which you are connected. For example, if you have three monitors, you can specify that the
remote desktop window appears on only two of those monitors. Adjacent monitors must be selected for the
multiple-monitor setup. The monitors can be positioned side by side or stacked vertically.
Beginning with HTML Access Web client 4. 5, the per device DPI synchronization is applied when the
multiple-monitor feature is enabled. If you are using two monitors that have dierent DPI seings, the DPI
seings on the HTML Access agent are set to the same DPI seing value used by the monitor of the client
machine that was used to start the HTML Access Web client session.
Procedure
1 Start Horizon Client and log in to a server.
2 In the desktop and application selection window, click the icon for the remote desktop that you want to
access.
3 To display the sidebar, click the sidebar tab.
4 Click the Open Menu toolbar buon at the top of the sidebar, select Display .
5 In the Display Seings dialog box, click Add Display.
N If the Display Selector browser window does not appear, add your Horizon server's FQDN
address into the Pop-up exceptions section of your browser's Content window.
6 Drag the Display Selector window so that it appears in the other monitor display that you want to use.
The message in the Display Selector browser window changes and a gray rectangular icon is added.
7 In the Display Selector browser window, click the + monitor icon to conrm that you want to use the
current monitor display.
The Waiting for other displays message appears on the current monitor display and the gray monitor
icon in the Display seings window in your primary display changes to a green color.
8 Click OK in the Display Seings window when you are done adding the monitor displays that you
want to use for the session.
The Display Seings window is dismissed, the Waiting for other displays message is cleared in the
non-primary monitor display and displays the remote desktop window.

Chapter 5 Using External Devices
9 To exit the multiple displays mode, press Esc and click Yes in the Exit the multiple displays mode
dialog box to conrm.
N Each time you have to use the Esc key in the remote desktop, open the sidebar tab, click the
Open Menu toolbar buon at the top of the sidebar, and select Send ESC.
You can play sound in your remote desktops and applications, but some limitations apply.
By default, sound playback is enabled for remote desktops and applications, although your View
administrator can set a policy to disable sound playback.
Take into account the following guidelines:
To turn up the volume, use the sound control on your client system, not the sound control in the remote
n
desktop or application.
Occasionally, the sound might go out of sync with the video.
n
In conditions of heavy network trac, or if the browser is performing a lot of tasks (I/O), sound quality
n
might be reduced. Some browsers work beer than others in this regard.
Using the Real-Time Audio-Video Feature for Webcams and Microphones
With the Real-Time Audio-Video feature, you can use your client machine's webcam or microphone in a
remote desktop or application. Real-Time Audio-Video is compatible with standard conferencing
applications and browser-based video applications, and supports standard webcams, audio USB devices,
and analog audio input.
Real-Time Audio-Video is supported only in Chrome, Microsoft Edge, and Firefox. The default video
resolution is 320 x 240. The default Real-Time Audio-Video seings work well with most webcam and audio
applications. For information about changing the Real-Time Audio-Video seings, see "Conguring RealTime Audio-Video Group Policy Seings" in the Conguring Remote Desktop Features in Horizon 7 document.
When a remote desktop or application is connected to the client machine's webcam or microphone, before
the remote desktop or application can use to the webcam or microphone, the browser might ask for
permission. Dierent browsers behave dierently.
Microsoft Edge asks for permission every time. You cannot change this behavior. For more information,
n
see hps://blogs.windows.com/msedgedev/2015/05/13/announcing-media-capture-functionality-in-
microsoft-edge.
Firefox asks for permission every time. You can change this behavior. For more information, see
n
hps://support.mozilla.org/en-US/kb/permissions-manager-give-ability-store-passwords-set-cookiesmore?redirectlocale=en-US&redirectslug=how-do-i-manage-website-permissions.
Chrome asks for permission the rst time. If you allow the device to be used, Chrome does not ask for
n
permission again.
When a remote desktop is connected to the client machine's webcam or microphone, an icon for each device
appears at the top of the sidebar. A red question mark appears over the device icon in the sidebar to indicate
the permission request. If you allow a device to be used, the red question mark disappears. If you reject a
permission request, the device icon disappears.
If Real-Time Audio-Video is being used in a remote desktop or application session and you open a
connection to a second desktop or application, and if a security warning appears (for example, if a valid
certicate was not installed), ignoring the warning and continuing to connect to the second desktop or
application causes Real-Time Audio-Video to stop working in the rst session.

Connect to a Server in Workspace ONE Mode
Beginning with Horizon 7 version 7.2, an administrator can enable Workspace ONE mode on a Connection
Server instance.
When Workspace ONE mode is enabled, you can connect to the server only through Workspace ONE Web
Portal. You will be redirected to the Workspace ONE Web Portal when you try to connect to the server
through HTML Access. After you connect to the server through Workspace ONE Web Portal, you can start
remote desktops and applications only through Workspace ONE Web Portal.
You might encounter the following problems when Workspace ONE mode is enabled.
You cannot connect to the server through HTML Access. You might not be able to reach the server, or
n
you might see a message stating that the server expects to receive your login credentials from another
application or server.
