A Windows Server 2003-based Dynamic Host Configuration Protocol (DHCP) server is running on a domain controller in a child domain. Although the DHCP Microsoft Management Console (MMC) snap-in shows that the status of the server is unauthorized, the only available button is Unauthorize. Sometimes, neither the Authorize button nor the Unauthorize button is available. Additionally, the following event may be logged:
Event ID: 1046
Description: The Dhcp/Binl service on the local machine, belonging to the Windows Administrative domain child1.domainname.com, 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. For more information, see Help and Support Center at http://www.microsoft.com/technet/support/ee/ee_basic.aspx
To work around this problem, trigger Active Directory directory service replication in the forest. Use the ADSIedit.msc tool to check the following Active Directory location from the root domain controller:
CN=NetServices,CN=Services,CN=Configuration,DC=DomainName,DC=comYou will see that the DHCP server object has been added.
Note When you check this Active Directory location from domain controllers that are running in child domains, you may not see the DHCP server object. This object may be missing because of configuration partition replication latency or because of other replication problems. The DHCP service can verify itself by using any domain controller in the forest. If replication has not finished yet, the DHCP server may not see the DHCP server object on a domain controller in a child domain.
