Core Operating System Division. DHCP Authorization problem - Event ID 1046 ★★★★★★★★★★★★★★★ John Howard -MSFTMay 18, 20052 0 0 0 I was speaking to a customer yesterday who was telling dhcp the specified servers are already present in the directory service me about a problem he was having with DHCP in his reasonably small office

network (something like three servers). He had recently upgraded to Windows Server 2003 and implemented Active Directory. Previously, he was working

in a workgroup and so you can understand it is quite a different situation now. The specific problem he had was that his Windows Server 2003 DHCP machine (also a file server), which had been https://social.technet.microsoft.com/Forums/windows/en-US/babd49b5-da0d-4838-9fcd-2591efa17dc5/unable-to-authorize-dhcp-server-event-id-1046-1059?forum=winserverNIS running quite happily until joined to the new Windows Domain suddenly stopped working. He showed me a screen-shot of the error which I've replicated through Virtual Machines below. (Click for a bigger image) The answer (if you know) is simple. You need to authorise your DHCP server in Active Directory. The reason for this step is to stop rogue DHCP servers appearing on the network. From the DHCP snap-in, simply https://blogs.technet.microsoft.com/jhoward/2005/05/18/dhcp-authorization-problem-event-id-1046/ select the server, right-click and authorise it. After authorising, you will see Event ID 1044 appear in the system log of the DHCP server indicating that it is not 🙂 authorised to start and is now servicing clients. You do not need to restart the DHCP Server service.

Should that "not" really be in there? Reply John Howard -MSFT says: May 19, 2005 at 11:40 am Well spotted Iain. Yes, the "not" should not be in there.

When trying to authorize DHCP server, it authorizes but the red cross does not http://www.kozeniauskas.com/itblog/2008/04/29/cannot-authorize-dhcp-server-in-the-domain-event-1046/ 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 http://www.anas.co.in/2009/04/event-id-1046-dhcp-error-dhcp-server.html 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 event id 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. event id 1046 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. :authorize, dhcp, Event 1046 5 Comments for this entry Paul October 21st, 2008 on 01:47 Thanks, nice work Reply Rob August 21st, 2009 on 17:53 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. Reply gon January 9th, 2013 on 17:02 grea
the DHCP server should be authorized in the domain by Active Directory, then only the DHCP server will be able to lease IP address for the clients in the domain.But sometimes you may face some troubles with the DHCP authorization. It may get unauthorized frequently in the domain. I have been searching for some troubleshooting for this occurance. and I found some uselfu stuff in Microsoft knowledge base.This error will log some events in event viewer. It is as follows :"Event Source: DhcpserverEventCategory: NoneEvent ID: 1046Date: DateTime: TimeType: ErrorUser: Not ApplicableComputer: ComputerNameDescription:The DHCP/BINL service on the local machine, belonging to the Windows Administrative domain domain, has determined that it is not authorized to start.

(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. "This issue may occur if there is an object conflict inside the Active Directory directory service configuration container.To troubleshoot this issue you have to install "adsiedit.msc " to any active directory domain controller in the domain, and do the follwoing troubleshooting. You will get adsiedit tool from windows server 2003 support tools.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, domain4. Right-click the objects, and then click Delete.5. Exit the ADSI Edit MMC snap-in.Veri
