Visual Studio 2005 SP1 includes support for integrated pipeline access which is great and I verified that it actually works for me on several projects.
However, I have one project where I cannot integrated pipeline debugging to work. I get this error:
---------------------------
Microsoft Visual Studio
---------------------------
Unable to start debugging on the web server. Debugging failed because integrated Windows authentication is not enabled. Please see Help for assistance.
---------------------------
... and yes I'm 100% sure that Windows Auth is enabled, and that permissions are set in the virtual directory (gave Everyone full access to be sure). I compared this site to the sites that run in module and handler configuration as well as all the authentication settings I can think of yet it still won't work.
I've also tried IIS 7 Request tracing on the debug attempt and it looks like it's choking on trying to access global.asax - in the FREB trace Authentication shows as not available - however if I run another failure request (say a page that doesn't exist) and I display the trace for it it properly shows an authenticated Windows Auth login.
There's more detail here:

I'm stumped but I would like to get this app running in integrated mode. Any ideas on what I could be missing or what else to look at?
Config:
