I have a 2008 R2 Remote Desktop Server. When I logged in this morning, I was presented the little notification flag "Windows must be restarted to disable UAC".
We have limited users with admin rights.
I suspect it was one of our software vendors who were logged in looking at our database last night, and emailed that they had trouble connecting to their own FTP server from our server "even attempting to run IE / Windows Explorer as Administrator". I suspect that after it didn't work when running in admin mode they tried disabling UAC, then gave up after it requested a reboot.
I have queried them about this but haven't had a response yet, but if they deny it I'd like to be able to prove if it was them. Making this kind of system wide security change without permission is totally unacceptable.
I haven't been able to find anything, but does Windows log when someone changes UAC settings?
Thanks
