System.UnauthorizedAccessException error in mscorwks.dll causing the application to crash

Question

My application pools continue to randomly crash in IIS 6.0 MS Debug Diag on kernel32.dll every time.

The entry point is always mscorwks! CreateApplicationContext + bbef, and the result is always a System.UnauthorizedAccessException exception.

Stack trace:

Does anyone know what this means and how to fix it?

Edit: The above stack trace turned out to be a symptom, not a cause. The above stack trace shows an unmanaged stack, but a problem has occurred in managed code. I used the steps in my answer below to dig into a crash dump and catch a managed exception.
