Thanks for the tip.

We run SQL Server 2000. I was pointed to the instance Security Page under SQL Server Enterprise Manager, where I could set the Log in Acct/Password. That set the Log In Properties for my service (MSSQL$svc), and the file permissions. The service started up under the domain\acct I specified.

I need to do this "on the fly" in an InstallShield Script. Could you point me to tool(s) to accomplish that?

Thanks very much.
