Creating snapshot RPC function call failed. Function name: [GetFreezeState]. Target machine: [192.168.x.x]. RPC error:The remote procedure call failed. Code: 1726
This is an Exchange 2007 Server running Hub Transport and Client Access roles, and is also in a WNLB with another identical server.
I believe the issue is due to the fact that the IP address listed next to Target machine is the WNLB address that is being shared with the other Exchange 2007 Hub Transport and Client Access server. It's not connecting to the hosts dedicated IP, and I'm not sure how Veeam is determining which IP to use. The backup completed without issue for the other server in the WNLB cluster, so I'm assuming it used the host address in that instance. It could have also used the WNLB address for HTCA1 and just didn't display a warning, I don't know.
The 2 servers actually consist of 3 servers
- HTCA Cluster <- Veeam is using the IP address of this cluster instead of the individual node.
