Server's DHCP

[linux00]

I have a Domain Controller in which I run DNS, DHCP, etc..
Well everything was working flawless until yesterday that the
server stopped the DHCP. The domain controllers DHCP has been authorized and the scopes are activated...However, it shows as unauthorized and when I right click to authorize it, the option is not available, but only the unauthorize. Any ideas, please help...

Did you check the event logs to see if there any errors related to the DHCP service? Start there first

 

[linux00]

Yes, there is an error saying "The DHCP/BINL server on the local machine, belonging to the Windows Administrative domain has determined that it is not authorized to start. It has stopped servicing clients." I must say that this is one domain controller, but its not the master domain controller.

Do you have the associated event ID? Try looking it up in eventid.net to see if you can find anything relevant

 

[linux00]

Event ID: 1046

Most comments indicate that you may have a "rogue" DHCP server on your network that is causing your issue

Hope this helps

The DHCP won't authorize, even though it appears on the authorized servers. It still shows red and not authorized on the MMC. Right-clicking the server in the MMC would only allow you to Unauthorize. I have restarted the DHCP service and no luck. I did see another server on the authorized list which are no longer domain controllers, I don't know if that has something to do with the problem... Any help

Linux00, as I have indicated, it seems you have another DHCP server on the network as per your last post. This is server is probably the main DHCP server now, that's why you can't authorize this one.
