I found this information while doing some network related investigations.
I thought I give it a try,may it could be useful:
You can check the last recieved Group Policy Update DNS suffix
in the key below.This key records the connection-specific DNS suffix
of the connection over which the Group Policy update was received:

- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows
\CurrentVersion \Group Policy\History\NetworkName

If the affected PC does not recieve Group Policy Updates it may
(just a possible cause !!) can be caused that the
last-recieved DNS key is empty.Update it with the correct Domain Name.

Note:
This issue was not tested or rechecked from my side.
The source of this infomation is from here:

So if you have further questions post them on this forum!
