NOTE: I was told in the Windows 7 forum to post this in the Server forum instead.
I'm having a strange issue on one of several Windows 7 (Ultimate x86) machines. This particular machine is a VM running in Hyper-V on a Windows 2008 R2 server (also a DC/AD/DNS/DHCP/WDS server). This is all within a Windows 2008 R2 active directory domain.
NOTE: I've changed my active directory domain name to the generic names "DOMAIN" and the domain controller machine name to "DOMAINCONTROLLER" in this post to keep my network details from being public knowledge. The actual domain and machine names have not been renamed on the network.
I'm noticing two symptoms that appear to be related:
- In the Event Log, I see (every hour) a System\GroupPolicy event ID 1058. The error code is 0x80090022 (2148073506) and is very cryptic "Provider could not perform the action since the context was acquired as silent.". It mentions that it could not access \\DOMAIN\sysvol\DOMAIN\Policies\{GUID}\gpt.ini
- This Windows 7 machine cannot access the DFS shares either which are \\DOMAIN\dfs. I get the message "An extended error has occurred."
Now, what is very strange is if I access \\DOMAINCONTROLLER\sysvol\DOMAIN\Policies\{GUID}\gpt.ini from the Windows 7 machine, the file is accessed fine. (DOMAINCONTROLLER being the windows network machine name of the DC). Likewise, if I use \\DOMAINCONTROLLER\dfs I can access the DFS hierarchy without any problems. (If I use the old Windows 2000 style domain name (without the .blah.blah suffix) it also works fine.)
If I ping DOMAINCONTROLLER or DOMAIN, both resolve to the correct IPv4 address (I'm not using IPv6).
The other 4 Windows 7 machines on the network are not having either of these issues.
I tried editing the lmhosts file to be sure DOMAIN was referring to the proper machine and all and it had no effect.
Still more baffling, if I run dfsutil /pktinfo I see "0:[\DOMAINCONTROLLER\dfs] AccessStatus: 0 ( ACTIVE TARGETSET )". dfsutil /spcinfo looks correct too.
I've done dfsutil /pktflush and dfsutil /spcflush as well as dfsutil cache domain flush, dfsutil cache provider flush and dfsutil cache referral flush.
Weird.
Any ideas? Solutions?
UPDATE #1: I should add that this error just began occurring on June 5th 2012 at 2:17AM. The Windows 7 VM's access to \\DOMAIN\SYSVOL and \\DOMAIN\DFS etc all worked fine prior to that time.
UPDATE #2: This just gets weirder and weirder. I restarted the "TCP/IP NetBIOS Helper" service and for a minute \\DOMAIN\SYSVOL worked but then it went back to "An extended error has occurred." Windows 2000 style \\SHORTDOMAIN\\SYSVOL and \\DOMAINCONTROLLER\SYSVOL both continue to work fine.
