The DHCP service could not contact active directory
DHCP server Unauthorized, Need to Authorize (Not in an AD environment)
We are starting to have some conflicts on other systems due to this. The main problem were running into is our phone system (which runs on a
workgroup and has its own DHCP server that handles all the phone ips) is not working.
Member of a workgroup) comes up, the following happens: The server broadcasts a DHCPINFORM message on the network. Any other server that receives this message responds with DHCPACK message and provides the name of the directory domain it is part of. If a workgroup DHCP server detects another member DHCP server of a domain on the network, the workgroup DHCP server assumes that it is unauthorized on that network and does not service requests. If the workgroup DHCP server detects the presence of another workgroup server, it ignores it; this means that there can be multiple workgroup servers active at the same time, as long as there is no directory service.
Even when a workgroup server comes up and finds itself allowed to run
(because no other domain member server or workgroup server is on the
network), it continues to probe DHCPINFORM every five minutes. If an
authorized domain member DHCP server comes up later, the workgroup server becomes unauthorized and stops servicing.”
The DHCP on the main server sees it as unauthorized, and tells it to shut
down.
Is there a way to authorize my workgroup dhcp server with the main DHCP
server so it does not shut down? When I go on our main DHCP server, and try to authorize it there, it tells me that the DHCP service could not contact
the AD (which is correct because were not running AD)
Any help would be appreciated….
