What do you want to use for mail on the win2k system?  Thunderbird?

I recommend downloading wireshark (was called ethereal) for win2k.
That helps me sort stuff out.

Can your win2k telnet into them?  Fire up cmd.exe and run telnet.
Have wireshark capture so you can see what you get.

I think you mean you can ping the host by sending an ICMP message.  I
don't know how you'd ping the TCP ports.

Yeah networking on windows is a can of worms.  Much easier for me to
configure linux but that may be because I am more used to it.

Wireshark is your friend.
