I'm wondering if there is an artificial limit on the number of sockets a windows process can open, if the limit changes across Windows versions what is the limit for XP? A link confirming your answer would be helpful.

    There is, of course, some limit.  Unfortunately, said limit is likely situational.  An off the cuff glance at anecdotal information would lead one to not expect more than a few hundred without explicit testing under rigorously controlled conditions.

    The most I recall hearing of under XP was somewhere around 2,500.

    Like cookre said, there is of course "some" limit.  What that is, however, I'm not sure... but this site/page seems to shed some light that may be relevant.  Take a look at section 3, for TCP connection attempts.  I'm not sure if it'll help you out or not, but doesn't hurt to mention, right?  It includes a link to a patch to remove that limit too...

    Hope it helps you.
