How to auto-disconnect dial-up with ICS?

Archived from groups: microsoft.public.win2000.setup (More info?)

I've got a home network setup with two computers- W2000 has a modem
and my dial-up internet connection and the other machine is a XP Pro.

I have ICS setup and the W2000 dials out when I open IE on the XP
machine.

However, upon closing IE on the XP (remote) machine, the W2000 does
not drop the dial-up connection. I imagine that it would drop it
after 30 mintes of inactivity just like it would for its own usage,
but my queston is this-

Is it possible to configure an auto-disconnect (say after 30 seconds)
if a client machine closes all internet programs?

TIA, Rich
