Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.

Resolution

Caution! Refer to the Disclaimer at the end of this article before using Registry Editor.

Complete the following steps to resolve the issue:

  1. On the affected XenApp server, open the Registry Editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Terminal Server\Install\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap, change the value of “IEHarden” to “0” (zero, disabled).

  2. Recreate the User Profile for all affected users so their profiles reflect the new registry setting on logon.
