title: DHCP Server not Authorized
body: <p>I have two Active Directory servers performing both authentication and DNS.
  One server is 2003 and the other is 2008.  It is my understanding that there is no primary Domain server in this scenario and that everything will replicate from 2003 to 2008 without issue.</p>
  
  <p>I have a 3rd virtual 2008 server which has been preforming DHCP for over 2 years without a problem.
  It is now appearing that I cannot properly authorize DHCP (Red downward arrow).
  When I attempt authorization, I do not get an error.  It simply does not function and appears to not be authorized. I also tried netsh for authorization.</p>
  
  <p>I have an error in the logs of the DHCP stating:
  "The DHCP Service failed to see a directory server for Authorization"</p>
  
  <p>One change that was made recently was that I tried to revive the old physical DHCP server for performing another service.  I changed the IP and the Computer name before I networked it. I have since turned it off, but I believe that this is when the problem began.</p>
  
  <p>What is the problem?
  Additionally, are one of the AD servers more primary in the authorization of DHCP, or are they of equal authority?
  Thanks</p>
  
  <p>Note:  I have removed all outdated entries regarding DHCP from DNS.
  Also, forest functionality level is set to Windows 2000, though we have nothing on our network older than XP.</p>
