I changed the DNS server information for several NetWare 5.1 SP8 servers
using the DNS/DHCP management console ver 6.5 SP2.

The next day, I unloaded DHCPSRVR. When attempting to load, I get the
following error:

Loading module DHCPSRVR.NLM
DHCP Server
Version 3.13e October 25, 2004
Copyright (C) 1991-2003 Novell, Inc. All Rights Reserved
SERVER-5.00-1: Loading Initiated at 10-17-2006 12:18:35 pm.
SERVER-5.00-21: Logger thread to update NDS is started.
10-17-2006 12:18:36 pm: DHCPSRVR-3.13-0
DHCP TCP processing thread cannot be started.
SERVER-5.00-68: DHCPSRVR terminated at 10-17-2006 12:18:37 pm.

This only happened on two of six servers. The others were also running
dhcpsrvr.nlm ver 3.13e Any suggestions on how to resolve this error so that
I can load the DHCPSRVR would be GREATLY appreciated.
