DHCP Dementia

By SynapsE_z ·
My server is confused and so am I. One day last week DHCP stopped functioning. No computer on the network could lease an IP. I have only one DHCP/DC on a small network. Everything else works as it should and I have since manually added IP addresses to the workstations.

The strange thing is that there are no obvious error messages and DHCP claims it's functioning properly. The only strange thing that I can point to is the name listed in the DHCP mmc. Normally, it would be <servername>[ip address]. However, when I open DHCP mmc, the name is listed as activedirectory.<scope-name>.local. This is weird because netsh correctly lists the name and so does AD sites and services. In fact if I go to add a managed server the correct name is listed and I can add it(still doesn't lease IP's). After a while when I check again the name reverts back to the activedirectory<scope-name>.local. I'm not even sure this is a problem with DHCP. This could be a symptom of something else but I've been unsuccessful so far. If anyone has any ideas why this could be happening please leave a post. I'll try anything at this point. Thanks.
