When trying to discover a workstation in RUM an error message stating "The RPC Server is unavailable" is displayed.
The workstation being discovered is unable to resolve the server acting as the RUM Console by NETBIOS name or Fully Qualified Domain Name (FQDN).
1.) Add the domain names suffixes to the DNS Settings on the workstation being discovered.
2.) Modify the host file and lmhost on the workstation so that it can resolve the RUM Console Server by NETBIOS name and FQDN
