   Thanks for the reply. I was hoping we could make the listener send the symbolic name to the client to resolve a problem we have with NAT (Network Address Translation). Some of our client machines are on the other side of a router doing NAT, so the client machines know the server by the same name, but a different IP address.

   When the listener tells the client machine the "real" IP address, the client attempts to use this and the communication fails. If the listener would report the name to the client instead of the IP address, the client would resolve it properly.
