Basically, the problem is that you have a PC running XP... it really screws with networks.
Good luck getting it to see the 2k computer! Make sure to kill the built-in XP firewall. It is wholey useless in any practical situation. All that it does is give you a huge headache trying to get networks running... you can disable it in the properties of the connection used in Network Connections. I believe it is in the Last tab.
As Starcrusade alluded to, you can not use mutliple PCs on the same internet connection through a hub. You must have a router (most routers have a hub or a switch built in). And no, having 2 separate connections with different IP addresses to DSL does not count...
I suggest using a build of linux as the server, rather than win2k server. There are some builds designed specifically to be used on PCs set up as routers. No need to buy an actual router, just a second network card for the comp to turn into a router. It can also act as a web server, mail server, print server, etc.
