The DHCP/BINL service has determined that it is not authorized to service clients on this network for the Windows domain: domain.com.
 
Primary DHCP server1
RAS server - server2 -> error occured on this server. I had to authorize the DHCP server on the RAS server to eliminate the error. I understand that I cannot have two DHCP servers...but why did this error occur in the first place. Is 'authorizing' different than actually server as a DHCP server?

One more note, the PUBLIC ip address of our servers (RAS and others) changed last Friday.

The authorization continues to fail although you exercise Q306925 and Q303351. A possible reason could be a misconfigured DNS entry in the TCP/IP properties. If the DNS is running on the same machine, verify that the IP of the local NIC(local DNS) is listed in the Preferred DNS server box.
(On a multihomed system this NIC must be listed at first under Advanced Settings in Adapters and Bindings.)
If the DNS is running somewhere in the LAN, verify that the IP address of that machine is listed in the Preferred DNS server box. In both cases perform the steps listed in Q306925 (Deleting and Reauthorizing the DCHP Servers)after you you change the DNS settings. In rare cases you have to reboot the system. In very rare cases you have to remove and reinstall DHCP.(Take care about the SP version).

A Windows 2000-based DHCP server in a Active Directory configuration needs to be authorized in order to serve DHCP requests. Use the DHCP administration interface to authorized the server (if the server is legit).

Dave Bronson
This error started occuring after I installed in the network a firewall acting as a DHCP server.

Simon Dallmair
I had the same problem, but my Server was authorized. The Microsoft article Q299363 helped me to solve the problem.

Árni Joensen
This problem can occur if the LDAP filter request for the DHCP server in Active Directory was incorrect. To work around this problem, use either of the following methods:
Change the IP address so that is has less than 12 digits.
Change the hostname of the DHCP server in lowercase, or create the DHCP server hostname value in Active Directory in uppercase.
See Q303525 link below.

One more question...one the RAS server, I assume that the DHCP server doe not have to running on the RAS box for the VPN clients to recieve a DHCP address from the DHCP server (which is running on another box, and is the AD controller)? or does dhcp forwarding have to be enabled somewhere on the RAS server?
