The Microsoft Exchange Replication service does not appear to be running.

Last week we had a major outage in our Exchange 2010 environment (28 multi-role servers in 2 DAGs). The provisioning system (based on Quest software) did some unexpected things after a restore of the provisioning database, resulting in (lots of) security groups in Active Directory being deleted. We were relatively lucky since the default groups (Domain Admins, Enterprise Admins etc.) were not deleted, but all Exchange Security Groups (in OU=Microsoft Exchange Security Group) were deleted.

These Exchange Security Groups can be recreated using the Setup.com /PrepareAD and Setup.com /PrepareDomain commands.

All seems to be running fine, but when executing PowerShell commands against a remote server (i.e. not the server being logged on to) would result in error message. For example, it was not possible to move an active Mailbox database from server1 to server2 in a DAG using the Move-ActiveMailboxDatabase command. When executing this command it would return the following error:

The Microsoft Exchange Replication service does not appear to be running on “computername”. Make sure the server is operating, and that the services can be queried remotely.
