Usually, when using Windows Authentication, the software (eg Internet Explorer) tries to use Windows Authentication, and if it doesn’t succeed (because the domain is untrusted, or because the credentials are not ok for example), it just popups a login window so that you can input your domain, login and password.

With sql Server Management Studio 2008, if I select ‘Windows Authentication’, the login/password boxes are autopopulated with my current credentials, and if I try to login, it says :

Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (Microsoft SQL Server, Error: 18452)

I never get a chance to enter my credentials on the server domain…

I know I can fix this by either joining the domain on my computer, or enabling ‘sql server authentication’, but that’s not what I want 🙂

Any ideas on how to solve this?

  1. try this: Use RUNAS to set your Windows Auth domain for database connections

    runas /user:domain\user “C:\Program Files\Microsoft SQL Server\90\Tools\Binn\VSShell\Common7\IDE\ssmsee.exe”   runas /user:domain\user “C:\WINDOWS\system32\mmc.exe /s \”C:\Program Files\Microsoft SQL Server\80\Tools\BINN\SQL Server Enterprise Manager.MSC\”'   runas /user:domain\user isqlw
