I have one windows server (2008 R2 datacenter) which is also our primary domain controller. Somehow, every time I apply new Windows updates to the server and reboot it, the server comes back and I could not log in as any domain users including administrator telling me "access denied". Then I had to shut down the server and boot back on and I am able to log in.
I also have a windows 7 workstation having the same issue. I had to reboot the workstation to the safe mode and then reboot it again to be able to log in.
Very weird! Anyone runs into the same problem by any chance? Any clue on this issue?
Thank you very much!
