Try running "PerfMon" -- IIS has counters for this sort of information. I
suggest reading MSDN documentation on the counter of interest and playing
around with PerfMon for a while.
If the issue is easy to reproduce -- can you give me EXACT instructions on
how to reproduce the environment that will illustrate the issue, as well as
the request sequence to produce the issue, I can try to repro.
If I cannot reproduce it using your instructions, there is no way for me to
troubleshoot it or have a developer look at it. So, it is to your advantage
to be detailed and not miss any important points (or possible, reinstall
using your steps to verify how easily reproducible the issue actually is).
Your statement of "static files" and "worker process failed to shutdown
within time limit" conflict with each other. Static file implies that no
processing is done on the server other than network IO -- which should not
"hang" -- so either your server is not really serving static files (for
example, you have an ISAPI Filter configured or a scriptmap for the file
extension or "*") or some other network IO is hanging. Your problem is
indicative of "something else" going on with the server outside of IIS.

First, the website is in it's own app pool with default settings. The site is extremely light...like maybe 1-2 users per day. But, when testing, I can reproduce this problem soooo easy. I don't know how to view the current connections to this specific site and how to look at the app pool real time. Any help would be appreciated.
