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)
