Unable to add a Hyper-v Host with RAS (Remote Access Service) enabled

Challenge

When trying to add a Server 2012 system to Backup Infrastructure as a Hyper-v host, managed server, proxy or repository, the operation fails with:

“Failed to check whether remote installer service is available" "The RPC server is unavailable" "RPC function call failed. Function name: [GetSvcVersion]” 

Cause

RAS services are installed on the Host OS. The RAS service creates an IP connection that is hard coded to be the first chosen. This prevents the Veeam installer service from properly installing on the host.

Solution

In order to add the host to Veeam, you will need to uninstall RAS role/services. It is best practice to keep the host OS as clean as possible. If you would like to use RAS (or other roles on the host), install those roles on a VM inside the host, and not on the host OS itself.
