ICS in the Registry

I would like to know if the time out setting for dial up network connections
is in the registry, and if so where i would find it please?
I am having trouble with a Broadband connection that is dropping out after
exactly 10 minutes but i cannot find any settings to stop this. I figure if
it is in the registry, i can disable it or increase it to something like 720
minutes to stop the problem getting in the way of using the Internet.
I do have ICS working. That shouldn't be causing this problem thought should
it?

TIA Chris
