Question : User name grayed out in SQL Server 2005 Server Management Studio

I am running the Microsoft SQL Server Management Studio for SQL 2005 on my local workstation.

When I start it, username is grayed out when choosing windows authentication as the Authentication mode.

Is there a way to select a different user name for authentication?

You would have to either login as the other user or start the program with Run As.

For example, Programs > Microsoft SQL Server > SQL Server Management Studio (right-click and select Run As).
