We just rebuilt our machine with server 2012, and it was working flawlessly and then randomly it started giving me this error if i would try to start up a machine. At first this was just an annoyance but now it is worrying me greatly. I have tried everything from logging on as the domain admin account to the actual server administrator account. Nothing seems to start these machines up, and I need them to start.
'Computer1' failed to start worker process: Logon failure: the user has not been granted the requested logon type at this computer. (0x80070569).
