Windows 7: Connecting windows 7 to internet via bluetooth via XP

Hello,



I have to lenovo laptops in front of me, the older one runs XP and the new one runs windows 7. The XP machine is connected to the Internet through a high speed Ethernet cable.

I paired the two machines together with bluetooth. And Now I am trying to connect the 7 machine to the internet through bluetooth through the XP machine.

I went to "Blutooth computer operation and settings" Of my XP machine.
there was "use your computer (old computer name) to connect to the Internet"
I clicked on connect.
Then I clicked Dial up.
It says Dialing for a few seconds and then prompts:
"Error 638 the remote server is not responding in a timely fashion."

any one knows how to solve this?
