     Hi Alan/Ray
     
     Please excuse my jumping into this conversation - but - I happen to
have
     same symptoms. The rpcping returns a 12007 error from teh client via
the
     internet but it works fine if I try it on the server direct
(proxy/exchange
     all on one machine).
     
     Whats more puzzling is that it's working for an existing client
machine so I
     suspect the server is all seup ok.
     
     Any hints?
     
     Many Thanks in Advance for any help,
     Dirk in sunny Tassie (Australia)
