Random denying of access to folders
Im having a recurring problem with what seems to be user account control being re-enabled after being disabled. Before i reimaged all our clients over the holiday we used to get random machines denying access to system folders when full admins were logged in. We used to have permission requests when running programs on those machines when they had worked fine in the past. When i reimaged everything this summer the problem disappeared until the last week or so when it has started up again. Im currently logged in with my setup account as normal which is an account with domain admin rights and is a forced mandatory profile. I am being denied access to the temp folder and denied access to deleting files out of the system32 directory unless i take control of them. This user account works perfectly ok on other clients and i dont get these problems. All the clients were reimaged barely a month ago and have been working perfectly fine until now.
I really dont know where to start to fix this problem. Any suggestions?
