to set up the connection sharing with the WinXP machine being the 'host'. In WinXP there's a wizard that creates a floppy disk which you can use on the ME machine to set the sharing up automatically.
All you need to do is set up a dial up connection to BT on your WinXP machine. To do this, go to start and click on 'Connect to' and 'show all connections'.
Now click on 'create new connection' under Network tasks in the left-hand pane. Follow the wizard to create the connection. All you need to know is the dial-up number, and your username and password for BT AnyTime. WinXP will automatically offer you the default modem as the one to use, and all you need to do is connect the modem to the phone line.
Once you've done all that you can run the connection sharing wizard in WinXP, and to save space here I'll advise you to click on Start and select 'Help and support'. Then type: Internet conection sharing into the search box. You'll see all the information you need, and if you get stuck you know where to come for help.
