This article was very helpful, and solved the problem I had been having with setting up the dial-up network. I had managed to set up the server and client, and they could connect, but I could not access the server resources, besides being able to ping the server. The answer was to set the IP address range to the next numbers following the ones used by the ADSL connection.
I can now dial-up from my office to home on the XP computer and access the internet; but my older computer running Win98SE is a problem.
On the dial-up setup on XP there is a checkbox "use Windows logon domain", which is unchecked. On Win98 I can find no such similar setting, and after connecting, I get a dialog box asking again for Username and Password, but also Logon domain. I don't have one, and not filling it in cuts me off.
Is there a way around this, or can I set up a user domain on the server that I can then enter from the client when logging on?
