Configure Dialup Server on WinME

Hi!

I am setting up a connection between my pc and my sister's using dailup connection. I configured my pc as the dialup server. But when my sister's pc(running on winXP) establishes connection, it always ask for the username and password which I do not know how to configure on the dialup server.

I have read an article on the internet about it saying that to configure a dialup server it must have the following network components:

*client for Microsoft Networks
*Dial-Up Adapter
*A network protocol that is common to both computers

I have enabled also the File and Printer Sharing. But still I was not able to establish connection.

Any idea? Please help me.
