One of my Windows Server 2003 DHCP servers has stopped functioning. The machine acts as a DC, DNS, File Server and DHCP server for one of my small offices. The rest of the services listed appear to be working normally.
The local management console of the machine gives no indication that there is a problem with DHCP, but if I try to reach the DHCP application from a remote console, I get the following message:
Cannot find the DHCP Server
The DHCP Server you specified cannot be located. The DHCP server might be down, there might be network problems, or the DHCP service might not be installed.
The error was: The DHCP Server Service is not running on the target computer.
To retry the connection, either press F5, or on the action menu, click Refresh.
The problem that I am having is that the server is simply not assigning addresses to clients. Clients that obtained addresses before the problem started are functioning normally, as are machines that are manually assigned IPs. The server does not respond to renew requests for addresses.
I have restarted both the machine and the DHCP Server service, but it hasnt made a difference. The machine seems to behave normally otherwise: reponsive to pings, RDP connections, etc.. I cant narrow down the time of the failure precisely, but I suspect it coincides with a power failure at the office over the weekend. Event logs don't reveal anything substantial.
