i have win2k pro and i was trying to play a game across the network, and for some ol' reason UDP (TCP/IP) wasnt working so i installed IPX on both computers and then used IPX to play... after installing it however i am not being able to upload or do certain things like send email, delete email, post in forums (btw im using a diff OS right now), etc etc...ive tried uninstalling the IPX but that doesnt help the problem.. besides how would installing IPX affect my internet like that??
