Unable to Manage one of 14 DHCP Servers

There are 14 DHCP Servers (2008 R2). One is a new server that was just upgraded from 2003 to 2008 R2, this is one of the last servers upgraded, thru the DHCP MMC, the DHCP server can be managed if you have domain admin rights but not if you only have DHCP Administrators rights. All of the other DHCP Servers work fine. I've checked DNS (Forward & reverse), WINS, unauthorized and re-authorized the DHCP server to no avail.

    Have you authorized this server as Enterprise Administrator ?
    If this is still not working you can try to unauthorize it again and open Sites and Services console using Enterprise Admin account and follow below steps:

    1) Select Active Directory Sites and Services root node
    2) From menu choose "View -> Show Services Node"
    3) Go to "Services -> Net Services" node
    4) In the right pane search for that DHCP server name and/or its IP address
    5) Select name and/or IP address if found and click right mouse button on the record. Choose delete

    when you delete all those records, try to authorize DHCP server once again using Enterprise Admin account. After all check if it is able to be managed by DHCP Administrators group members

    I have performed the unauthorized, remove with ADSI edit and re-Authorize multiple times.

    Each time the same results. The server does authorize and is servicing workstations, it can be managed if the account has domain admin rights, it can NOT be managed if the account only has DHCP Admin rights.  This is the only DCHP server having this problem.

    Re-Verified the account has Enterprise Admin rights.

    Problem resolved, it was a local permission issue on the server.

    This server was not a domain controller and was missing the DHCP Admins security and had to be manually added.
