I recently stumbled across this realy good article about restricting access to the RDP/ICA protocol on a Citrix or terminal server through WMI. You don’t have to be a programmer to understand the code, since it is realy easy to use and implement. With just one line of code it is possible to add/remove a user or group from the ICA/RDP protocol, thus allowing for better security for your servers.

If you have to setup or manage several terminal servers, this article can ease your life.

The article can be found here.
