2507 CU2 - Started having users unable to login with "The Group Policy Client service failed the sign-in. Access is denied." after I updated Delivery Controllers and FAS (same day) to 2507 CU2. I hadn't seen any of these other than corrupted profiles before. Now I am getting several per day across the environment. I saw there was a fix for this very message in 2507 CU2, is it possible Citrix didn't get all of the situations that cause it? Requires a restart to clear the session on that server. Users are able to log in to other servers. Until Citrix figures it out, anybody have a better way to allow the user to login to the same server with out a restart?
