I'm running IIS Crash & Hang Agent on that box right now.

Here's the tail of 4872_inetinfo.log:

(1308.1a30): Unknown exception - code 000006b5 (first chance)
UnKnown_Exception

These exceptions correlate in number and time with warnings in Event log.
Any ideas? One additional piece of info that might be helpful is that this
box has Terminal Services in App Server mode.
