Backup Exec and Exchange 2007 SP1 - CCR backup network problem

[Ilkka]

We have Exchange 2007 SP1 CCR installed in Windows Server 2008. On each node we have 4 networks and 4 NICs:

1. Production
2. Heartbeat
3. CCR replication
4. Backup

Now we are trying to run backups over the Backup network, but it fails with error:

"The Media Server was unable to connect to remote machine EXCHANGE_CLUSTER_NAME using subnet 10.147.x.x/27 on network interface Backup."

Backup is tried to run against active node at the moment. We have tried also passive node.

We have done steps mentioned it this document:

And if we run backup for non-clustered Public Folder server in same organization, it works fine.

Are there more things to do to get it work in CCR clusters?

Can you backup the Exchange cluster by IP when using the Backup Network?  You will need to add a user defined selection for the IP to test this.

No. I tried with cluster IP, but result and error message is same.
