1.I am networking an old existing win98sp computer that has dial up internet access and a printer attached with a new XP computer. I have file and printer sharing and internet connection sharing. With both computers on, something is automatically dialing and connecting to the internet on the old computer. If I disconnect, it redials after a few minutes. I can't figure out what it is.
2. If there is no internet connection, can I establish a connection from the new computer ( through the old computer) or do I always have to dial up from the old computer?
3. The win98 computer seems less stable with the networking activated. Are there configuration tweeks that will minimize problems?

I am new to networking so these are likely to be very basic issues. Thanks, Gary
