In an effort to assist me, one of my staff changed a policy setting on our 2008 Standard Server using gpedit.msc
The setting changed was Windows settings / Local policies / User Rights Assignment / Allow Logon Through terminal Services
He changed this to Administrator and now as a consequence, none of the terminal services users can access the system. I cannot set it back as it appears to be locked.
I am logged on as the administrator and have tried running gpedit.msc as the administrator but no luck.
I would appreciate assistance as I have 20 users coming in the morning and they can't access their system.
