Ron,
This is what happened to us:

Moved over a few websites that use Access to a brand new more powerful W2K3
server from a W2K server. These websites had functioned flawlessly for a
couple of years.

After the move, after periods of time (ranging from 10 minutes to 2 hours)
the server would stop serving ASP pages and would only serve static pages
until it was restarted.

I was getting the following error in the Application log:
"ISAPI 'C:\WINDOWS\system32\inetsrv\asp.dll' reported itself as unhealthy
for the following reason: 'ASP unhealthy because 100% of executing requests
are hung and 36% of the request queue is full.'."

I paid for a support incident with Microsoft and after a few days of them
looking at the dumps they sent me a BETA version of a fix to the MS Jet.

The file is a beta fixed msjtes40.dll. The server has been functioning fine
now for about 24 hours.
