OK, so the problem is not with the DHCP server?
Are all of "a few dozen machines" in your LAN subject to this problem randomly?
Repeatedly? How many total computers in the LAN? Any differences in hardware
or software? Physical location?
How often does this problem occur, as opposed to not occur?
You "see" this happening thru a packet sniffer running against the DHCP server?
Does this happen constantly? Do you see anything in the Event Log for the
problem computers?
What happened a month ago? Software upgrade? Hardware upgrade? New computer
deployed?
