In a 60 user domain running two domain controllers Windows 2008 R2 & 2003, one user has developed a problem logging in. She is on a Win 7 pro box. She has been using it for two years with no problems. Nothing has recently changed in the network.
On Friday, she reported not being able to login. She rebooted and nothing worked. Without restarting her PC, I logged onto her Pc as the domain administrator with no problem. I logged off and then she was able to login normally. She has the same problem again this morning.
Her AD account was not locked out Friday and it's not locked out this morning.
