ISAPI Extensions

Hi,

i have a few ISAPI extenstions (Visual C++ with MFC) that generate pages
from tables in a SQL server database. These
extensions have been working great for a few years. (NT4, IIS3 or IIS4). Now
my customer
has bought a new server (Win2k advanced server, IIS5), and now these
extensions don't work anymore.

Sometimes the first page is generated correctly, but after that the
webserver complains with an Internal Server Error 500.

Somebody any idea what could be the cause of this, and/or how to tackle this
problem?

Thx

Herman

It is absolutely impossible to even guess at what is wrong with your ISAPI
Extensions -- a 500 error is a generic response indicating "something bad
happened". I mean, in a gross simplification of your situation -- you might
have code that tries to dereference a NULL pointer on the second request.
Best way to figure this out is attach a debugger to the process and debug
your ISAPI Extension to see what is going wrong.
