Reporting Services Form Authentication - w3wp.exe kernell32.dll Er

Hi,
I have developped a Form Authentication extension for Reporting Services
which used to work just fine on a certain server. Suddenly, for "no apparent
reason" (I had not personnaly changed the configuration of anything on the
server), Report Manager stopped working (but the Report Server still is
working).
I don't see anything wrong (i.e. no ERRORS) in the Reporting Services
LogFiles but in the Windows Event Log I see the following error:
"
Faulting application w3wp.exe, version 6.0.3790.1830, stamp 42435be1,
faulting module kernel32.dll, version 5.2.3790.1830, stamp 424377d2, debug?
0, fault address 0x00015dea.
"
I do get my form for authentication but once authenticated, I never reach
the Folder.aspx page of report manager, instead, I get a "The page cannot be
displayed" ("Cannot find server or DNS Error").
I've tried using Debug Diag on w3wp.exe and here is what I get on the crash
dump report:

This exception originated from msvcr80!_CxxThrowException+46.

It doesn't feel like the code in my extension is the problem given that it
used to work and I haven't changed anything. Also, it doesn't seem like my
extension is throwing the exception, so it feels more like a configuration
problem somewhere.
Note that if I revert back to the original configuration (without my form
authentication extension), everything goes back to normal, so it really feels
like the problem is in the configuration of the ReportServer/ReportManager
folders.
The server has Windows Server 2003 Service Pack 1, IIS 5.1 and the extension
is coded with .NET 2.0. As specified earlier, I don't think that this
configuration has changed recently. I could show what I changed in the
Reporting Services .config files but first, I want to see if the dump gives
any clue (given that these .config files were working not so long ago).
Any clues or suggestions that I could try?
ThanksHi,
I'm still hoping for an answer. Is this the right place to post an issue
like this?
