Shadow Options are Unavailable in the ICA Listener or Management Server Consoles
Article ID: CTX692980
Updated On:
Description
-
The shadowing options on the Advanced Connection Settings dialog box of the listener are unavailable or restricted.
-
If the shadow options are unavailable, all options were restricted during installation.
-
If some of the options appear and some do not, the missing options are the ones restricted during installation.
-
The shadowing options for the RDP listener might also be unavailable.
-
The Citrix Management, Access Management, and Discovery Services Consoles might not display the Shadow option.
Resolution
Complete the following steps to resolve the issue:
-
Reinstall XenApp.
-
Remove the Windows 2003/2008 Policy. To remove the policy in Windows 2003, complete the following procedure:
- Type gpedit.msc to open the Local Group Policy Editor.
- Navigate to Local Computer and/or User Policy > Computer and/or User Configuration > Administrative Templates > Windows Components > Terminal Services > Sets rules for remote control of Terminal Services user sessions.
- Remove the policy.
-
Check for the existence of the following registry value:
HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\Terminal Services\Shadow
If the value exists, delete it and restart the server, so the option must be available. If the value returns after restart, it indicates that there is a Group Policy attached. -
Install an ICA Client (Citrix Receiver) on the Server if not currently present.
Note: The Citrix install process does not log the selected shadowing options. The CHFarm process does not allow the shadowing selection to be altered.
Installing an ICA client without the pass-through /SSON option causes the user who is initiating the shadow session to enter the user credentials before the shadow session is initiated.
Problem Cause
-
An ICA Client is not installed on the Server.
-
Recreating the ICA Listener does not resolve this issue. The registry cannot be manipulated to alter the original selection. These selections can be altered only if reinstalled.
-
"Shadowing restrictions are permanent. If you disable shadowing, or enable shadowing but disable certain shadowing features, the restrictions cannot be changed at a later time."
-
A Windows 2003/2008 Policy is enabled. The following are the details of the policy:
- Windows 2003: In the Group Policy Editor, the location of the policy is Local Computer User Policy > Computer and/or User Configuration > Administrative Templates > Windows Components > Terminal Services > Sets rules for remote control of Terminal Services user sessions.
- Windows 2008: In the Group Policy Editor, the location of the policy is Local Computer Policy > Computer and/or User Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections > Sets rules for remote control of Remote Desktop services user sessions, as shown in the following screen shot.
