Jack Vamvas does a thing I wish we could do innately in SQL Server Management Studio:
I am logged onto my desktop with my primary Active Directory ID. I need to log onto a SQL Server with SQL Server Management Studio (SSMS) with another Active Directory ID – the alternative ID has valid SQL Server security privileges on the target SQL Server.
How can I log onto the target SQL Server with the alternative login , remain on my desktop and use the alternative Active Directory ID ?
By the way, if you need to connect to a remote domain but your machine isn’t a member of that domain, add the /netonly flag to Jack’s answer. I’ve had to do this before when VPN’d into a network with a laptop not registered on that domain. Another tip is that, if you do this a lot, you might want to create a Windows shortcut which includes the full command.
