Under the following conditions,

1. Win 2003 server

2. Strawberry Perl (Not activestate's distro)

3. I do not use the listen parameter.

then IO::Socket::INET "works."

If I use the listen parameter, then the code errors out with an "unknown error" message. The code provided in the comments works because the listen parameter is not used.

Thank you for the code. It works great.
