Here's a good one for the gurus out there.

I'm building a custom application that will query a web-service to get
data. The users are broken into two groups. Group 1 is the in-office
staff that are connected to the network. Group 2 is the remote staff
that must connect via dial-up connection to the Internet to use the
web-service.

The user (a.k.a. boss) would like the application to automatically
close the dial-up connection if there hasn't been any activity for 10
minutes. Anyone like to share a way to programmatically launch a
dial-up connection and then close it from within my application? Even
pointing me to KB articles would be good.
