Can't authorize DHCP

I have a site on our Server 2003 based network that is no authorizing DHCP. We had a previous server that was working fine but we had to replace it with another one but this one can't get to authorize  DHCP. The new server is a DC with a different name than his predecessor. I tried uninstalling and reinstalling DHCP. Demoting and promoting the server and trying to authorize again and nothing. We format and reinstall the OS on the server and nothing. We reconfigure our Firewall and still nothing. Any idead on where else to look will be greatly appreciated

when you try to authorize DHCP do you get any errors or if you look in the event viewer are then any errors listed pertaining to this?

Assuming your replacement from the old server to the new went ok...
I mean you didnt just rip the server out and put in the new one and expect all to go well right?  Did you dcpromo the old machine?
How did you transition to the new hardware?

Normally DHCP wont authorize because there is another dhcp on the network.  You dont have a router handing out dhcp do you?

We did a dcpromo before getting rid of the old one.

Do you have a static IP on the server?

Yes, we have a static IP address on the server.

And your sure no other dhcp is going on anywhere else on the network?

As far as I know no. I thought the same thing but this is the only server on this subnet. The workstations does not have any DHCP enabled and the PIX firewall has DHCP disable. I checked two or three times.

Is the DHCP service started?

menendezaAuthor Commented:
Yes, it was started. Actually I found what the problem was. A very old server was still authorized in AD. I did a clean up and was able to authorize now.

I dont think that answer should be accepted.  My post 21762430 asks if there was another dhcp on the network

No problem to give the points to him/her. I actually thought he meant like a secondary DHCP somewhere else in the network and not within the authorized DHCP's in AD. My apologies for the misunderstanding
