I cannot for the life of me figure this out. I know that there should be an "NTService" account....but I just cannot find it no matter what I try. When I try and use Domain\Administrator as the Logon creds for SQL Server Express, it runs for a while.....then crashes and stops. Can someone help me figure this out please? I am very much beginner level with SQL. Thanks.
This is my issue, but the answer is for a full SQL server, not SQL EXPRESS:

"NT Service\MSSQL$SQLEXPRESS" either does not exist on the machine (or Domain?), or if it does, I cannot find it or link to it for some reason.
