Hi,, I need assistance here we are currently running exchange server 2003, the exchange was down for almost a week, and managed to bring the one at HQ up and running, the two remotes sites exchange servers not opening up services with error "Topology Discovery failed event id 2114" this happened after the server running all FSMO roles went down and taken away for some time to an extend that it exceeded tombstone lifetime, i have moved all roles to another server for benefit of more questions i have attached dcdiag report also Domain Controller Diagnosis Performing initial setup: Done gathering initial info.

Hi, To resolve this problem, verify the following: The default domain policy or the default domain controllers policy is not blocked by a "No override" configuration on an organizational unit object or on the domain object. The Manage Auditing Security Privilege user right in the default domain controllers policy is applied to the Exchange Enterprise Servers group. The computer account of the affected Exchange server is included in the Exchange Domain Servers group. Also for complete details read this article please. http://support.microsoft.com/kb/919089 Regards. Shafaquat Ali.

Hi Shafaquat I have rechecked that > default domaincontrollers policy and domain policy is not blocked > on Exchange Enterprise Servers group - manage audit security is indeed applied > Mail Server is part of Exchange Domain Server group I have checked almost everyone to troubleshoot that , but seems it does not work Regards,<steve
