Spent a bunch of time trying to hunt down the following: Event Source: Userenv Event Category: None Event ID: 1054 Date: 3/12/2008 Time: 8:42:38 AM User: NT AUTHORITY\SYSTEM Computer: ServerName Description: Windows cannot obtain the domain controller name for your computer network. (An unexpected network error occurred. ). Group Policy processing aborted.
We were getting this on a bunch of new servers, all running Win2003 R2 64bit. It's also showing up on a number of XP machines. Finally decided to just open a ticket with MS. The problem is apparently a "slow link detection", which is of course abundantly obvious from the errors. Per MS, we did the following reghacks: Registry subkey: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\System Value name: GroupPolicyMinTransferRate Value type: DWORD Value Data: 0 Registry subkey: HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\System Value name: GroupPolicyMinTransferRate Value type: DWORD Value Data: 0 Note: if the "System" key doesn't exist, please create it under HKCU\Software\Policies\Microsoft\Windows & HKLM\Software\Policies\Microsoft\Windows first. >From the MS tech support rep: "It is possible that certain firewall program (such as Windows Firewall) is installed on all your machines and configured to block the normal ICMP packets. Sometimes it may be also caused by some models of CPU. For example, there is a known bug with AMD Opteron Processor driver for Windows XP and Windows Server 2003 Version (x86 and x64 exe) 1.3.2.16, which allows the system to automatically adjust the CPU speed, voltage and power combination that match the instantaneous user performance need. The slow link detection depends on the CPU clock to calculate the speed. However, it may fail when working along with AMD Opteron driver. Recently we have received many reports that this known bug in the AMD CPU driver often causes the group policy detection failure. AMD has provided a new version of driver to solve such similar problems. You can get this point from: http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_871_9033,00.html"; We've done the reghack, not updated the drivers as yet. ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~
