I performed an update on some client machines, and after the update, all I get when I try to log in is "Access is Denied." This message appears when I log in as Domain admin, local admin, or any users whose profiles are stored on the local machine. The only way for me to resolve this is to log into safe mode and perform a system restore to just before the updates were installed. Any info on what update might have caused this issue? This issue occurs no matter what windows OS is running on the client machine.
