Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I have two Windows Server 2008 SP2 machines (TFS and TFSBUILD). Periodically, the TFSBUILD server shares (\TFSBUILD\ShareName or \TFSBUILD\C$) become unresponsive to requests from Windows Vista (Server 2008) and Windows 7 client requests. Windows XP machines are still able to connect.

No events in the server log indicate any problem. A simple restart corrects the issue temporarily, but it always returns.

It is not this http://support.microsoft.com/kb/948732 (we aren't using that software).

This does not appear to be an issue with SMB 2.0. Per @Maxwell I tried disabling it on the server and on the Windows 7 and Vista stations:

sc config lanmanworkstation depend= bowser/mrxsmb10/nsi
sc config mrxsmb20 start= disabled

All anti-virus software has been disabled, firewall is disabled by policy. No other network activity is affected.

The TFSBUILD server is a virtual, running under Hyper-V (x86 guest on an x64 host). The host has the same OS version and SP.

Any help would be greatly appreciated.

We've decided to just rebuild the server (this time as 2008 R2). Thanks to all for the input. –  Peter LaComb Jr. Jun 10 '10 at 16:26

Maybe this has something to do with SMB 2.0, you could try disabling it on the server and on the Windows 7 and Vista stations:

sc config lanmanworkstation depend= bowser/mrxsmb10/nsi
sc config mrxsmb20 start= disabled

This may be a workaround...

Trying that now. –  Peter LaComb Jr. Jun 4 '10 at 16:06
    
Excellent suggestion, but no luck. –  Peter LaComb Jr. Jun 7 '10 at 13:45
    
Was Symantec Endpoint installed on the server? –  Maxwell Jun 7 '10 at 14:09
    
No, in fact, I thought that was the KB I linked to, but I'll update it. –  Peter LaComb Jr. Jun 7 '10 at 15:23
    
Per @DrZaiusApeLord I should have RTWFA - Adding reg. entry now to see if that fixes it. –  Peter LaComb Jr. Jun 8 '10 at 18:41

hm. can you disable/remove IPv6 and all others unnecessary filters/services on TFS/TFSBUILD servers ?

you can look at WinXP network configuration to decide what to disable ...

You also need to put in the reg key on the server to disable SMB2. Then you will need to reboot the server and all your clients.

There seems to be a somewhat related question here. One answer that sticks out is to check the "File and printer Sharing for Microsoft Networks" option on the network adapters. However, this would likely cause it to never work, not stop working after a while.

I'd suggest you get Wireshark on the server and start a trace of the network traffic. Check to see what it looks like when XP clients connect to a share, and when the Win7/Vista clients connect (both when it works and after it stops working). Hopefully you'll find some obvious missing piece when it's not working that can help lead to the actual cause.

You're right - if F&P sharing wasn't installed it wouldn't work at all. Already installed Wireshark. I'll post traces of working/non-working soon. –  Peter LaComb Jr. Jun 7 '10 at 15:30
    
Most av software isn't really disabled until you uninstall it! I'm pretty sure this is true for mcafee not sure of others. –  tony roth Jun 7 '10 at 21:32
