Our 5.1 (sp6) server keeps having trouble with DHCP. The server
itself is
set to static, but runs the Novell DHCP server. Server works fine for
a
while, then stops delivering addresses. To fix the problem, we simply

unload and reload the dhcpsrvr.nlm.

Any thoughts on what could be causing this?
We only have about 20 workstations (Win2K and XP Pro) and have 50
addresses
set aside in the DHCP pool.
Single Server, Single Subnet.
Cisco 48 port switch.

(I don't think this is related, but we recently had a problem with
workstations being disconnected and their login not clearing from
monitor.
It took a reboot to clear the login.
I think this was related to some new HP workstations we got with
gigabit
Broadcomm cards. Once we removed those from the mix the connection
issue
seems to have ceased.)
