SYMPTOMS

Event Category: None

Event ID: 1046

Date:

Time:

Type: Error

User: Not Applicable

Computer:

Description:

The DHCP/BINL service on the local machine, belonging to the Windows Administrative domain, 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.



CAUSE
This issue may occur if there is an object conflict inside the Active Directory directory service configuration container.



RESOLUTION
To resolve this issue, follow these steps:  Start the Active Directory Service Interfaces (ADSI) Edit MMC snap-in. To do this, follow these steps:  Click Start, click Run, type Adsiedit.msc, and then click OK. Click Tools, and then click ADSI Edit.  In the console tree, expand the Configuration container, expand CN=Configuration, expand CN=Services, and then expand CN=NetServices. In the details pane, you may find objects that resemble the following:

CNF:,CN=NetServices,CN=Services,CN=Configuration,

</li> Right-click the objects, and then click Delete.</li> Exit the ADSI Edit MMC snap-in.</li></ol>

Verify that the DHCP server becomes authorized after active directory replication is complete.
