We have two forests, one of which is a resource forest, with one-way trust from the resource forest (Forest B) to the main forest (Forest A). We have no problems using Windows XP desktops in Forest B to login to user accounts in Forest A. When we add Windows 7 or Vista desktop systems in Forest B, the users in Forest A cannot use these machines in Forest B to login to their domain in Forest A. The error message we get is "The security database on the server does not have a computer account for this workstation trust relationship". This error only occurs with Windows 7 and Vista systems. We would appreciate any help in resolving this problem. Thanks.

Hi, after checking the issue, it seems this is a general Windows Server related issue. As this forum focuses on Windows 7 specific issues, this inquiry would best be posted to Windows Server forum: http://social.technet.microsoft.com/Forums/en-US/category/windowsserver The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.
