FBW,
Why disable? Just follow the instructions to give addresses
ie "go to "Control Panel" then "Network" then "TCP/IP->your Network card" then "properties" then "Specify an IP address" Add an IP address to your network card (ie 10.1.1.1) or (192.1.1.1) and the subnet mask 255.255.255.0
Those on a network may prefer to use 192.168.0.1 and subnet 255.255.255.1 "
As I said earlier I added the 192.1.1.1 and the 255.255.255.1 addresses and they worked for me perfectly.
Perhaps you disabled the Dial up adapter? Just try the addresses rather than disabling.
Good luck!!
