I have a windows 2003 domain. I have a vista computer that when logging into the domain I get the trust relationship between workstation and domain has failed. I am not able to disjoin the domain and rejoin it back. How can I fix this issue? Is there a command that I can run?Gerald

HiError message when you try to join a Windows Vista-based client computer to a top level domain (TLD) that has a purely numeric suffix: "An Active Directory Domain Controller for the domain <DNS domain name> could not be contacted"Microsoft Hotfix available here. Please download and install it.http://support.microsoft.com/kb/947228Hopes this help!Deva

Hello Gerald,You can use Netdom.exe to reset machine account on the Windows Vista box to the domain.Please refer to:How to use Netdom.exe to reset machine account passwords of a Windows Server 2003 domain controllerhttp://support.microsoft.com/kb/325850As you mentioned, you cannot disjon the domain, please check to verify that the DNS setting on the NIC of the client is pointed to the internal DNS server properly. Besides, when you try to disjoin the vista box, does the diaglox pop up to let you input a credential?Thanks.This posting is provided "AS IS" with no warranties, and confers no rights.
