Hello everybody, when I try to access to the domain I get this message (only with the client windows 7, the clients windows xp go well) "The security database on the server does not have a computer account for this workstation trust relationship" after 1 or 2 reboots, I can log on...I have tried to join and rejoin to the domain, change the fqdn...i lost my hope :-( what can i do to fix this error? Thanks

Hi, According to your description, I suggest to perform these tests to troubleshoot the issue: 1 Check if any PGOs are applied on machine. 2 Remove the Windows 7 from AD and add it again. 3 Temporally disable firewall on Windows 7. If the issue only occur when join the domain, the issue should related with Windows Server, maybe GPO. Furthermore, about the error “The security database on the server does not have a computer account for this workstation trust relationship”, You may try to change domain from FQDN to the short domain name and Logout and log back in as the domain user. Regarding this issue, you could also refer to the following article: Error: The security database on the server does not have a computer account for this workstation trust relationship In addition, you can also contact Windows Server form to check if any server settings lead to this issue: 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.
