I run MS Small Business Server 2003 and for some reason my DHCP Server services stopped running - why?  Also when I restarted it, my laptop on the network still couldn't log on so I 'restarted' the service and then it could log on.  .

The most common reason the SBS DHCP service stops is because it detects another DHCP service on the network.

The event logs in event viewer will tell you the IP address of the rogue DHCP server.

DHCP usually stops on SBS if it finds another DHCP server on the network, such as on a router.

You generally cannot have two DHCP servers running on the same network and SBS will fight with the router then give up and DHCP on the server will stop.

Do you have DHCP enabled on your router?

No - just checked my router settings and it's not set up as a DHCP Server.

Did you check the event logs on the server?

It may have just stopped running!  As Demazter has suggested - check your event logs for the reason.

It could be corruption on DHCP database.

First stop DHCP service and backup  systemroot\System32\Dhcp somewhere else and copy systemroot\System32\Dhcp\Backup to systemroot\System32\Dhcp and start the dhcp service.

The other option is that the DHCP folder gas not been excluded from your antivirus software, this can also cause the service to stop.

I appreciate all the posts - those that said to check the event logs put me on the right trail in finding the offending IP address - but it was only when I disconnected each device, one by one, that I found the offender was my son's Mac laptop, and then it turned out that it had checked a setting 'Internet Sharing' which meant the laptop was acting as a kind of server passing on an IP address wirelessly.  Unchecking that setting solved the problem.
