Explanation

This Warning event indicates that Microsoft® Exchange Active Directory® Topology service did not find the mentioned domain controller in the Sites container in the Active Directory directory service. This situation can occur for the following reasons:

  • The Active Directory Topology service cannot locate the domain that contains the DNS server.

  • The Active Directory Topology service cannot find the DNS name.

  • The Active Directory Topology service cannot find a writable Naming Context in Active Directory.

If other Exchange services start and run, this warning can be ignored. However, we recommended that this warning be fixed by following the steps listed in the User Action section.

   
User Action
