Cannot Authorize DHCP server in the Domain (Event 1046)
by Andrius on Apr.29, 2008, under Microsoft
Here is a problem that had to fix yesterday.
When trying to authorize DHCP server, it authorizes but the red cross does not disappear and the server does not provide any IPs to the clients. Although DHCP console on the server and DHCP console on the domain is showing that the server is authorised. Only when you restart DHCP service on the server, in the system event log you receive Error with Event ID 1046
The DHCP/BINL service on the local machine, belonging to the Windows Administrative domain “your_domain_name”, has determined that it is not authorized to start. It has stopped servicing clients. The following are some possible reasons for this:
This machine is part of a directory service enterprise and is not authorized in the same domain. (See help on the DHCP Service Management Tool for additional information).
This machine cannot reach its directory service enterprise and it has encountered another DHCP service on the network belonging to a directory service enterprise on which the local machine is not authorized.
Some unexpected network error occurred.
To resolve the issue at first unauthorize DHCP server and run ADSI Edit as described in KB938456
Most likely you will find duplicate names for the DHCP server you are trying to authorize. Delete those entries and try to authorize the server again.

This was a great fix!! I had this problem(similarly)for some time. The member server would not authorize with teamed NICs. If I removed the team it would Authroize and bind to one of the IPs, but would not work with the dual NIC’s teamed. I followed the instructions and deleted the entries as noted, but I had to take it it one more step to get it to Authorize and get the Red Down Arrow to change to the Green Up Arrow. I had to remove the DHCP server role from the server and then reinstall it. After I did that and went through the configuration wizard to set up the scope and activate it, it Authorized immediately and binded to the one IP Address on the Teamed NIC’s. Thanks so much for your help here. You are the first person I’ve found with an answer on this.

I am trying to do this to resolve my DHCP error issue
To resolve this issue, follow these steps:1. Start the Active Directory Service Interfaces (ADSI) Edit MMC snap-in. To do this, follow these steps:a. Click Start, click Run, type Adsiedit.msc, and then click OK.
b. Click Tools, and then click ADSI Edit.
2. In the console tree, expand the Configuration container, expand CN=Configuration, expand CN=Services, and then expand CN=NetServices.
3. In the details pane, you may find objects that resemble the following:
CNF:,CN=NetServices,CN=Services,CN=Configuration, domain
4.Right-click the objects, and then click Delete.
5. Exit the ADSI Edit MMC snap-in.
I am using windows 2008 server and cnnot find those object. I also have the same error.
