Securing Windows 2008 Citrix or Terminal Servers

Loopback GPO

This allows you to apply user-level group policy to individual computers (i.e. the terminal servers). This will only apply to the terminal servers and doesn’t apply to the users PCs. Create a GPO and apply it to an OU containing the Citrix servers. Enable the loopback mode as shown below.

Make sure the permissions of the GPO apply to authenticated users and the citrix\terminal servers. I usual set a deny permission against domain admins to make sure they do not have this policy applied.

Preventing access to the command prompt and registry tools are an important setting.

 

Restrict Access to Folders from the Start Menu

Remove Pinned Server Manager and Powershell shortcuts from the taskbar
