TS + Citrix Troubleshooting

Group Policies - GPOs

When configuring a Terminal Server, Group Policies should be your first choice, rather than using the Terminal Services Configuration tool. The main advantage is that the settings will be applied to all servers in your farm, ensuring identical settings on all servers.

A crucial option in any TS-related GPO is loopback processing. This setting allows you to define a set of user settings, which will only be applied to users when they log on to the Terminal Server, without affecting them when they log on to their workstation.
 

The basic steps to use a GPO to configure a Terminal Server:

1. place the Terminal Server (not the users!) in a separate OU
2. create a TS-specific GPO
3. configure the GPO to use "loopback processing" with the "Replace" option (see KB 231287)
4. link the GPO to the OU which contains the Terminal Server machine account
5. add the Terminal Server machine account to the security list of the GPO
6. add a User group to the security list of the GPO (or keep the default entry for "Authenticated Users" if you want the settings in the GPO to apply to all users)
7. modify the rights for Administrators on the GPO: select "Deny" for the right to "Apply this policy" (see KB 816100)
