In Windows 7 there is an option to enable a run as context menu by holding down the shift key when opening the start menu. When I select the run as option a credentials dialog is shown, but it doesn't allow me to specify a domain like I can when I am using runas from the command prompt. The domain defaults to the domain that I am logged into.

Does anyone know how I can launch an application where I can enter the credentials from another domain? I tried domain\username but it doesn't work.

"doesn't allow me to speficy a domain", is it greyed out? – AdminAlive Dec 7 '09 at 22:36
there is not domain textbox just a domain label. I tried putting it\username and I see the domain label change to "it" but the login fails. – Kevin Dec 10 '09 at 6:07

Actually, it should be a backslash:


I know the original poster said he already tried it but, actually, when I use this syntax in the credentials dialog I see the name of the domain (just under the password box) change according to what I type before the backslash (Windows 7 x64).

+1 I can confirm this. Start typing DOMAIN then \, as soon as you hit \ the domain will change to the new domain you specify. – Darren Hall Dec 8 '09 at 3:51
I just don't get. I just tried again and when I type domain\username I see the domain label to change to what I specify but the credentials fail. One thing I did not mention was that this does work fine from the command prompt using this syntax: runas /user:it\kblakeley /netonly "C:\Program Files (x86)\Microso ft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\Ssms.exe" – Kevin Dec 10 '09 at 5:47

Maybe I'm totally off here but something in the back of my head tells me that username@domain should work.

Simply prefix the domain name followed by a / then your username in user box. Example:


I think this trick works for all MS Windows credential authorization boxes.
