Thanks for your response. I am not quite sure if that's what he meant. Anyway I have two GPO's. One for computer settings including loopback enabled -Replace and a separate GPO for user settings. The strange thing is that when I use the GP modelling wizard the policy works (in theory) but when I use the GP RSOP wizard, the policy seems to ignore the entire user policy. I have disabled user policy in the Computer GPO and computer policy in the User GPO.
I will have to look at GP operational logs. I am sure there is another Registry setting that allows you to look at even more detailed GP processing logs. It's out there in the WWW so I need another search for it and set the registry and gather the logs to see what's going on.
I will report back on this issue and put it all here so that others can benefit from it.
Funny thing is we have 4 Citrix policies ( two pairs), one pair for two separate OU's. One for a older farm and one for a new farm - Citrix Cloud. the old policy which looks very similar to the new one works flawlessly. the new one set up very similarly just doesn't. Curious.
