Can someone recommend a good strategy for troubleshooting IIS that is hanging on Windows 2008?
Normally, I check the following in Process Explorer:
-
CPU
-
Disk I/O
-
Context Switch Delta
However, in certain situations all of these values are low and yet IIS is hung up.
Is there anything in Process Monitor (sysinternals) that should raise a red flag?

When IIS is not responding but it does not look like it is doing anything, it could be that it is waiting for something. The actual problem will often depend on how your application is programmed. Here are a couple of examples.
Check the Httperr and IIS log
