Hmmm. Are you sure that you are posting to the right list here ?

Hello
I really hope someone can help me with this. I have been trying to figure it
out for days and I am beginning to go mad!
The issue I am having appears to be very similar to
https://issues.apache.org/bugzilla/show_bug.cgi?id=45063. It might even be
the same issue.
Note I can recreate the problem on various flavours of Windows, and in IIS 6
& IIS 7.
Details of the issue:
I have a web application which lives under the "Default Web Site" in IIS 6,
and which has its own app pool. The redirector (isapi_redirect.dll 1.2.28)
lives under the DefaultAppPool.
The user would log into our web application (which uses our app pool) and
everything works as expected. If he then uses functionality which uses the
redirector (and the DefaultAppPool), w3wp.exe will probably crash. (I say
"probably" because sometimes it works without error).
Note everything works fine (i.e. there is no crash) if I run the
DefaultAppPool as "Local System"; the problem only seems to exist if I run
the DefaultAppPool as "Local Service" or "Network Service".
Details of the crash:
In the Event Viewer I can see the following -
Faulting application w3wp.exe, version 6.0.3790.3959, faulting module
ntdll.dll, version 5.2.3790.4455, fault address 0x0004f053.
And if I catch the crash using Debug Diagnostic Tool -

There is nothing obvious in Process Monitor which explains what is causing
the error.
Do any of you have any ideas what could be causing this? Any advice would be
greatly appreciated.
