one of our Windows 2000 server domain changed after that MSSQLSERVEROLAPSERVICE is not starting.
This is the error message we are getting Error 1067: The process terminated unexpectedly. In even viewer below message is shown: The MSSQLServerOLAPService service terminated unexpectedly. It has done this 11 time(s). The following corrective action will be taken in 0 milliseconds: No action.
Have you changed the service accounts? If so, did you do this just in the services MMC snap-in, or did you use the SQL Server configuration manager? There's more to it than just adding a different account/password, and the SQL Config manager does all that work for you.
