This is a back to back DMZ scenario. Server publishing rule [SERVER1 - RPC Ports(135/TCP)] that maps 10.10.x.x:135 TCP to 10.250.x.x:135 for protocol [RPC port (135/TCP)] failed because the port on the external interface is being used by another application. The Firewall service failed to bind socket for the server on the firewall since another process is using the same port. Check for any other process using the same port and terminate if necessary.
