>>Does anybody know how to get ICS (Internet Connection Sharing) to automatically disconnect from the phone line when a remote computer closes it's connection? I've looked at the MSKB #Q230108, but that doesn't seem to help. It seems to only apply if you're on the machine running ICS, not one of the remote connections.

Ed:

When ICS is enabled, you can no longer change that property. It's disabled. That's the first thing I thought of, too, but no go. :( I'll have to see if I can change that when ICS is not started. Thanks!
