I ran into a bit of an issue today regarding the MS SQL Sever 2000 NT Service not successfully starting (over and over) after I had change the Administrator account's password. This, of course, became abundantly clear after checking the system event log.
Some how, I don't know why yet without doing further research on msdn, this also changed the logon for the MSSQLSERVER service in the services administration snapin.
Of course this was immediately remedied by changing the service log on back to the local system account instead of the administrator's account. How it got that way, I still have no clue without more research. If any one reading this has any ideas as to what would cause this, please do leave a comment, or email --> email@example.com. Thanks everyone!
