Exchange 2007 : Error: The Exchange server address list service failed to respond
During a DR simulation I recently came across the following error on an Exchange 2007 CCR cluster:
Error: The Exchange server address list service failed to respond. This could be because of an address list or email address policy configuration error.
The issue was that the System Attendandt Service had lost connection to the domain controller to which it was using. For some reason it did not automatically onnect to another DC. All other Exchange Functions were working, but management of users, groups and system objects was impossible.
To resolve this issue simply restart the Exchange System Attendant Instance service for the cluster using the Cluster Administrator tool.
This will allow the service to re-attch to an available Domain Controller.
