[Tutor] Socket connection refused

[Nick Lunt]

Error nr 10061 seems to indicate that there is too much load on the
server, and the recommended fix is to increase the timeout, but that is
when applied to SMTP/HTTP but I would expect it to be the same for all
IP based servers.

I have done the same server/client program as you a couple of weeks ago,
I created it on linux, then emailed it to my work and ran it fine on my
win2k box there, so I doubt it's a windows issue.

I have had problems with py2exe on windows and linux tho even tho the
programs were fine. I still haven't got my head around py2exe yet, I
suspect it's more complicated than I think and Im too busy learning
python to bother with it at the moment ;)

Have you tried running the server and client from the windows command
prompt ? It would be interesting to know how that goes.

Cheers
Nick.
