I actually had complete trust in ISA. That was what boggled me. I've been running it for over 2 years, multiple builds and playing with rules, etc. I knew everything was right and there was no reason, from ISA's perspective, that it should not be working. Was a hard one to find though, I found one obscure error that tipped me off, took almost 2 weeks to surface.

That was quite an interesting find. Good to hear that its not ISA's fault. Poor ISA, its the "sin eater" of network connectivity issues :) Thanks!

Everything I described below was related to a problem with the web proxy. After a couple more weeks of watching and tracking errors, I discovered that the BIOS ACPI (MSI P3 motherboard) of the replacement machine was trying to read/write to memory space used by the web proxy service. It caused unpredictable behavior and occasional crash of the web proxy. BIOS update fixed the ACPI and all the errors, proxy crashes and random problems went away. Sometimes the problem is right at the front door instead of the upstairs hallway closet. I had to work at this one. Best Regards, Dan Bartley o unsubscribe send a blank email to $subst('Email.Unsub')
