I have a problem with a server here. We can't logon via RDP out of hours using *any* of our admin accounts.
We can logon to the console however using the same accounts.
When we try using RDP we get a generic "Username and Password incorrect" error. The same details get us on to the console without any problem.
None of the accounts have any logon hour restriction on them, and if we create a new account with all the normal permissions on that server via the console, it cant logon via RDP.
Come monday at 9am it's all back to normal.
These accounts CAN log on to our terminal services servers (2003 and 2008) once their account is created so there can't be any logon restriction on the account level.
Can anyone think of a reason why you couldnt log on to a specific server during out of hours periods but you could still log on to other servers on the same domain?
