I'll try it next time the problem happens. Hope it works with SSL.

What I noticed is that when a hang appears, not even a record in the IIS log file is made until the hang clears up. All the while ping works just fine. I guess what I really want is to know when the IIS received the connection, but before running any ASP.NET code. That would be super helpful in narrowing down the problems.
