Found the problem. Just not sure why it is a problem, yet.

It appears that in the Virtual Directory page there is a field called
Application Protection. If we set this to Low (IIS Process), asp pages work
fine. When we had it set to Medium, it would not even process ASP pages.
Not only would it not process the pages, it would return no error pages. As
soon as we changed it to Low, if I put in a page that didn't exist (when it
was an asp page), I got a message back. If it was a higher priority, I
would get no message back for asp pages, but I would for .htm.

On my other machine, I don't have this problem. I can set it to High and it
processes the same pages just fine. It is the extension that causes the
problem. I could take a simple hello page and just change the name from
hello.htm to hello.asp, and it wouldn't process it. It would never come
back.

I don't have the problem on my other server, which is also using the default
settings (as is the problem server). I have the Application Protection to
High without any problems

I have the identical ASP settings (including asp script timeout of 90
seconds) - the problem is it never times out.

Not sure why it is happening as it is, Low will solve our problem (at least
temporarily), so we will go with that now.

Thanks,

Tom.
