Bringfried,
You could try giving the IP number of the remote host rather than the
hostname. The error message implies that IDL isn't seeing your change in
DNS settings when you change them - this is common to lots of programs
which read them at startup and remember them.
Of course, using IP number is dangerous in case the machine changes IP
number one day so you may want IDL to do a lookup as it starts and store
the IP number internally for the session and use the number for all
socket calls rather than the name.
Thanks,
Allan
