WMS2011 Domain Logon / Network Issues

Question

We have recently installed 3 MS6200 Series HP MultiPoint Servers for a school and we are having a sporadic problem with one or more of the servers losing connectivity with the domain, preventing users from loggin on to the clients (t150 zero clients).
I forget the exact wording on the screen, but basically after a while the server will stop allowing users to logon on to the system as they cannot contact the domain controller. The issue might then resolve itself a hour later, or maybe after a reboot. The
strange bit is it might affect any number of the three Multipoints at any time, but other windows clients or multipoints can logon onto the domain perfectly.
Any ideas???
Thanks,
James

Hi James,
We were experiencing the same problem, but I opened a case with Microsoft and they figured out what was wrong.  I had more than one DNS server listed - my own internal one and I had added 8.8.8.8 for good measure.  This was a problem.  When
we removed the 8.8.8.8 and left just my one DNS entry the problem went away.  
(Control panel/Network and Sharing Center/Change Adapter settings
Right click on your connection, choose properties.
Click on TCP/IPv4 (unless you are using IPv6...) and choose properties
Make sure there is only a Preferred DNS server listed.)
They also looked at my DNS server and found that I had old entries for a previous server that had been retired and cleared them out - but I believe that the ultimate solution was to remove the "Alternate DNS server".
Let me know if this helps!
