Guest Nico Fourie Posted July 10, 2007 Posted July 10, 2007 Hi All I hope I can find a solution to my problem on these news Groups. I decided recently to implement Exchange 2007 server into my domain. I have the following layout: - Single Active Directory Forest - FSMO roles are on current 64 Bit Server except Infrastructure Master is on 2003 32Bit machine. - DNS is still on 2000 Server and DHCP still on 2000 Server both Domain Controllers. Here is my problem, since I installed the 64 Bit Server I have been getting the following error every 5 minutes in the application log in event viewer: Userenv Event ID: 1054. Windows cannot obtain the domain controller name for your computer network. I have checked all the following: - IP configuration for correct DNS. - I can access all SYSVOL shares on all other DC's. - I can ping the 64Bit server from all other DC's and from itself. - I have run the RSOP admin tool and noticed that the Policies are disabled on 64bit but enabled on 32bit! - I have followed the steps in KB article 290647 to check Policy share permissions. - I have enabled Bypass traverse checking with correct permissions. But I am still getting the error Userenv Event ID: 1054. Windows cannot obtain the domain controller name for your computer network. Every 5 minutes. I might be totally blond but am I missing something. Highly appreciated. Nico Fourie
Guest Nico Fourie Posted July 10, 2007 Posted July 10, 2007 RE: Userenv, Group Policy problems with Server 64Bit To whom it may concern. I have finally found the sollution to my problem. The Problem was caused by the AMD Opteron 2x Dual Core CPU's you can find the KB article here: http://support.microsoft.com/kb/938448/en-us I would also recommend checking the following article if it still does not resolve your issues: http://support.microsoft.com/kb/290647/en-us especially if you have a mixed environment like I had mentioned above. Now it is off to install Exchange 2007, wish me luck!
