We are having intermittent issues with a terminal server 2008r2. At some point it prevents certain users from connecting giving: "An authentication error has occurred. The Local Security Authority cannot be contacted"
So far the only solution is to delete the AD user and recreate.
I deliberately entered the wrong password 3 times and it locked the account out on the DC. I then logged into the same TS as admin (no issues logging on) and opened ADUC on the terminal server. I pulled up the user and it did show that the user was locked out. I then reset the password telling it to unlock the user. The password appeared to reset however the user was still locked out.
I also tried connecting to Exchange OWA and was unable to log in as that user. Something seems to have corrupted on the AD User. This only happens to users logging into that one terminal server account.
Any ideas would be appreciated.
