I have such problem. When I've installed WINS and DHCP on the PDC server it seems that something works bad because neither WINS nor DHCP is starting and the communicates about that are:
event 7001 - the Windows Internet Name Service service depends on the NT LM Security Support Provider service which failed to start because of the following error: after starting the service hung in a start-pending state.
(Above is the same in DHCP server starting also)
event 7022 - the NT LM Security support provider hung on starting
The computer is IBM Netfinity 5000 with Windows NT 4.0 & SP6a
