SQL Server 2008 Windows Auth Login Error: The Login Is From An Untrusted Domain

- 1 answer

When attempting to connect to a SQL Server 2008 Instance using Management Studio, I get the following error:

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

I can login using SQL Authentication without problem. I've been getting this error all of a sudden. I have Mixed Mode Authentication turned on.

Does anyone have any experience with this?

Additional Info: 64-bit version of SQL Enterprise Edition On Windows 2003 Server



The issue was caused by a down Active Directory Server, which of course could not authenticate the Windows account. Thank you for your assistance.
