I have programmed a Windows Service in C# which should connect to an SQL-Server 2005 Express Database with `System.Data.SqlClient`.

As Microsoft prefers to use Windows Authentication over SQL Authentication I tried to connect to the database with Trusted Connection / Integrated Security.

However that doesn't work as I get a:

> 
> System.Data.SqlClient.SqlException: Login failed for user
> 'NT AUTHORITY\LOCAL SERVICE'.
> 
> 
> 

Is it possible to login with a different Windows Account?
