Hi all.
I have a strange occurrence at the moment, whereby users loose access to trusted sites, the wallpaper set by GPO disappears to be replaced by a black screen and single sign on to our intranet site stops working.
the "fix" so far is to either,
1.) delete the HKLM key for Group Policy Objects then reboot and all works again. Or failing this.
2.) rename the user profile, log the user in again and everything works like a charm again.
Is there someone that can guide me in the right direction to find a solution to this bane in my existence?
