If telnet works fine, then it's probably not a firewall issue. The error
you're getting is EINVAL, which usually indicates some kind of parameter
error to a system call. You didn't say whether you tried this with a more
recent Windows version- it could be that the weirdness Ruby does to massage
its Unix-like I/O calls doesn't work on NT4. I would also try it with a raw
IP address, just to get DNS out of the loop. Ruby definitely does handle DNS
weirdly.
