Hi,
I'm new to this least as I'm new to using purify.
I'm using the last purify eval version downloaded from Rational
site in order to evaluate if purify will help to solve our ISAPI
dll bugs on CGEY Intranet (Cap Gemini Ernst and Young intranet).
I'd like to purify an IIS ISAPI filter dll.
So I have generated a purified version of my dll, but IIS doesn't
want to load it, telling that it "cannot load controls".
I thought it was due to the Purify viewer window.
So, I've enabled IIS to "interact with the dektop" in the windows
control panel service, but again it didn't load the dll (but no
specific error message this time).
I've found and executed a procedure in Purify FAQ telling how to
instrument the IIS server, but the purified version of IIS server
crashes (inetinfo_pure.exe). Below is the textual export of the
Purify window, with the errors detected before the server crashes:

Thank's for any suggestion on how to workaround these problems.
