Can you change the login for a service in SQL Server?
Let's try this explanation... When you use SQL Server Configuration Manager to change the logon for a service, it does not "add" that domain user to SQL Server. It adds the domain user to be a part of the local user group that is defined for that service. If you change the logon for the service again, the old domain user will be taken out of that group. Note: You should not be using a domain account that would login to SSMS as a service account. So this allows you to elevate the proper privileges to the domain account without having to specify security settings for it in SSMS.
