Run SSMS as different Windows user

When connecting to a server from SSMS using Windows Authentication, you are limited to using only user which you used to log on to Windows. For example, if you login using User1 on Windows and launch SSMS, you can only use User1 to connect to a server from SSMS as shown below, the User name box is grayed out:


To use a different user without logging of and logging in as different user on Windows, you can use RunAs command to launch an application under different user’s context.

The general syntax for RunAs is as follows:

RunAs /user:DOMAIN\UserName ProgramName


To Run SSMS as different Windows user:

1. Go to Start -> Run,

2. Type following command in text box and press enter, this will launch command prompt to get user’s password:


3. Provide user’s password and press enter:

Enter the password for VGAJJAR\User2:


This will launch SSMS under User2‘s context.


Using this method you can run multiple instances of SSMS side-by-side under different user contexts:



To get more information about RunAs parameters, type RunAs /? at command prompt.

Hope This Helps!

    I often need to run under user credentials that belong to a customer domain from my laptop (that is part of my consulting company’s domain). I find that the sysinternals tool shellrunas lets me do this nicely. First, it has a “net only” option which means “only present these credentials to other computers, ie on the network”. Also, it allows you to right click an application shortcut and choose “run as – net only” and then prompts for creadentials. Here is a link to the utility: http://technet.microsoft.com/en-us/sysinternals/cc300361
