Hello!
I've a problem with RPC. I tried a very simple RPC-example from web (a
message server) for understanding how the stuff goes (I've never progammed
rpc before), but I always get this error message at svc_register when I
start the server:
Cannot register service: RPC: Unable to receive; errno = Connection reset by
peer
I've administrator rights on the machine (Windows 2000 Professional SP4) and
the RPC service is running. Cygwin sunrpc-package is installed.
Does anybody have a hint?
Thanks!
