I have setup a secondary server - however upon browsing to the "Protected Servers" on the primary I receive the following error:

I have tried refreshing (Updating data sources) with no luck. Firewall rules are all in place and verified traffic between hosts (no packet loss). DPM Writer and DPM Access manager both restarted on Primary both set to automatic/started. The "Protected Servers" are file servers (volumes). In addition both hosts were restarted. Ideas?
