Kind of confusing since this is erratic...

Is there a forwarder being used? Try changing that to 4.2.2.2 to see if it
works.
Also insure Secure Cache Against DNS Pollution is checked (DNS properties).
Any services on the workstations turned off?

Check the HOSTS files on the workstations, make sure they haven't been
altered. Almost sounds like that funky QHOSTS virus, but not really sure, so
just in case check it. Also look to make sure in the reg that the HOSTS file
being used is the one in the default system32\drivers\etc folder and not no
other one in the system.
