Installation and Setup Guide

n
If you are using a security server, verify that you are using the latest maintenance releases of
Connection Server 6.x and Security Server 6.x or later releases. For more information, see the View
Installation document.
n
If you plan to use a secure tunnel connection for client devices and if the secure connection is
congured with a DNS host name for Connection Server or a security server, verify that the client
device can resolve this DNS name.
To enable or disable the secure tunnel, in Horizon Administrator, go to the Edit Horizon Connection
Server Seings dialog box and use the check box called Use secure tunnel connection to desktop.
n
Verify that a desktop or application pool has been created and that the user account that you plan to use
is entitled to access the pool. For information, see the Seing Up Virtual Desktops in Horizon 7 or Seing
Up Published Desktops and Applications in Horizon 7 document.
I If end users have a high-resolution display and will use the High Resolution Mode client
seing while viewing their remote desktops in full screen mode, you must allocate sucient VRAM for
each Windows 7 or later remote desktop. The amount of vRAM depends on the number of monitors
congured for end users and on the display resolution. To estimate the amount of vRAM you need, see
the View Architecture Planning document.
n
To use two-factor authentication with Horizon Client, such as RSA SecurID or RADIUS authentication,
you must enable this feature on Connection Server. For more information, see the topics about two-
factor authentication in the View Administration document.
n
To hide security information in Horizon Client, including server URL information and the Domain
drop-down menu, enable the Hide server information in client user interface and Hide domain list in
client user interface seings in Horizon Administrator. These global seings are available in Horizon 7
version 7.1 and later. For information about conguring global seings, see the View Administration
document.
To authenticate when the Domain drop-down menu is hidden, users must provide domain information
by entering their user name in the format domain\username or username@domain in the User name text
box.
I If you enable the Hide server information in client user interface and Hide domain list
in client user interface seings and select two-factor authentication (RSA SecureID or RADIUS) for the
Connection Server instance, do not enforce Windows user name matching. Enforcing Windows user
name matching will prevent users from being able to enter domain information in the user name text
box and login will always fail. For more information, see the topics about two-factor authentication in
the View Administration document.
n
To provide end users unauthenticated access to published applications in Horizon Client, you must
enable this feature in Connection Server. For more information, see the topics about unauthenticated
access in the View Administration document.
Clearing the Last User Name Used to Log In to a Server
When end users log in to a Connection Server instance for which the Hide domain list in client user
interface global seing is enabled, the Domain drop-down menu is hidden in Horizon Client and users
provide domain information in the Horizon Client User name text box. For example, users must enter their
user name in the format domain\username or username@domain.
On a Windows client system, a registry key determines whether the last user name is saved and displayed in
the User name text box the next time a user logs in to the server. To prevent the last user name from being
displayed in the User name text box and exposing domain information, you must set the value of the
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\dontdisplaylastusern
ame registry key to 1 on the Windows client system.
