Some of my dhcp clients have stopped being able to obtain dhcp
addresses. I can assign a static address to them and they work. I
can assign dhcp addresses to other clients in the same subnet and they

work. The clients are Windows NT SP6a, Novell client (4.80, 4.81,
4.83, etc...).

DHCPSRVR is running on NW5.1 SP5.

I have tried changing the Novell Clients, updating DHCP to 3.12c,
updating TCP to 5.83k.

Any suggestions?
