Exchange Extension 80004005 Error on Child Domain
Posted on April 10th, 2008 | 4 Comments »
When trying to edit user profiles on an Active Directory child domain the action would cause the Users and Computers MMC interface to hang before displaying the following Exchange Extension error: “The operation failed. ID no: 80004005 Microsoft Active Directory – Exchange Extension”. Clicking OK then opens the profile without the Exchange tabs.

This is caused by the way the Exchange snap-in looks for the DC of the child domain. Instead of using the FQDN it’s trying to resolve the host name. For example if your parent domain is contoso.com and the child domain is sales.contoso.com with a Domain Controller of DC1.sales.contoso.com make sure you can resolve DC1 without the domain suffix. If you are using WINS then add it to your WINS server, if you are straight DNS then add a HOSTS entry on your local machine resolving to the IP of the child domain DC.

Thanks for your Great support
I fixed the exchange issue immediately based on your information
You can also add to the DNS search list. The DNS search list will by default include the stub domain, but if you have multiple domains on your network or child domains, adding the other search
Adapter->Properties->tcpip/Properties->advanced->DNS tab->”append these DNS suffixes in order”.
cheers!
I corrected the above by given the user the appropraite priveledge in active directory and computer of the main domain controller (server2008)
Mitch’s solution (adding the Exchange server’s domain and the child domain to the DNS suffix list) worked for me. Thanks!
