I have a NT4 server that is responsible for DHCP and WINS services. A little while ago we had an error on the network that 'corrupted' both the WINS service/db as well as DHCP service itself. WINS could be restored but when I try to start the DHCP service, error 2140, an internal windows error occurs. I have checked the registry for corruption, uninstalled TCP/IP to refresh the configuration parameters and investigated leading zero's in the registry setting for the local IP address which is a known NT4 server problem. Any ideas?

Uninstalling TCP/IP won't necessarily do anything to help the DHCP server service. My advice would be to completely uninstall the DHCP service, reinstall it, and then reinstall your latest service pack. If you want to take the extra time on the chance it might fix the problem, you could try simply reinstalling SP6a and it might fix your problem. Otherwise, a complete uninstall and reinstall is advisable. You will need to do this of course at a time when you can reboot the server. Unless you have a very large network, I wouldn't worry too much about trying to preserve your DHCP database - simply recreate the same scope and options when you reinstall and your workstations should be able to get leases without any trouble. Hope this helps!

I do not advise playing around with DHCP and WINS too much as you may get problems further down the line.

Save any information you might need and then
uninstall the DHCP service and reinstall the service and the service packs.
Re enter your information for scope and reservation and restart the service.

Once you've determined the services works porperly let it run.

Schedule a task every day at say 1:00 am that will stop the service backup the database and registry key and restart the service.
Do the same for the Wins service it will give you and accurate backup in case semothing like this appends again.

Refer to MS Knowledge base for procedures on backing up the databases.
