Problem

Adding an Exchange database availability group (DAG) fails with an error if all of the Exchange servers in the DAG are rebooted at the same time after the Agent for Windows is installed.

Error Message

The server was unable to complete the requested operation.

A communication failure occurred when attempting to connect to this server. Some common causes for this error are: the computer name is typed incorrectly, the computer is not powered on, a Backup Exec agent is not installed, or the network is improperly configured.

Cause

After the Agent for Windows was installed on the Exchange servers in the DAG, a reboot was required for all of the servers in the Exchange DAG.

Solution

After the server reboots, run the Add Server wizard again to add the Exchange DAG to the list of servers in the Backup and Restore tab.
