We currently have a setup where a large number of citrix servers are located in a separate forest at our data center for one of our customers. There is a forest trust between the forest at our company and the customers forest. The customer has a log in script that is set in to run in their default domain group policy. The problem is that when they log into the citrix servers through the trust it tries to process that script and it is creating very slow log in times.
I need to find a way to disable this script from running when they log into the citrix servers. I was thinking about enabling loop back processing but again, I only want this change to affect the citrix servers.
How can I block this script from running when they log into only the citrix servers? Will loop back processing solve the problem or is there another change I can make locally to each of the citrix boxes that will solve the problem? I need to avoid making forest wide changes. I would prefer making changes to the local policies of the citrix servers only.
