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.

HTH,

Thanks Mythran!  For some reason all I could find was for the
MarshallSoft component (which would've been the last resort).  Then
right before reading your post I found
http://www.developerfusion.co.uk/show/1920/1/ so I'm sure one of the
two will work.

Thanks again!
