I am running Visual Studio 2005 Professional:
Microsoft Visual Studio 2005
Version 8.0.50727.762  (SP.050727-7600)

I am trying to remote degug an ASP.NET application (targeting .NET Framework 2.0) that has been deployed in debug mode to a Windows Server 2008 x64, that has IIS6 Management Compatibility installed. The application is running under an application pool with managed pipeline mode set to "classic" and Enable 32-bit applications is set to "True". I have administrator rights on my XP (x86) development machine and on the server. 
Here is what happens:

1. I remote desktop to the server and start a remote debugging monitor session (using the Win32 version).
2. I run the web application in the browser on my XP machine.
3. In visual studio I do the usual Debug>Attach To Process specifying the w3wp.exe (Type: T-SQL, Managed, x86)

I can then see in my output window, the 'w3wp.exe' (Managed) debug symbols being loaded and then after a few seconds I get the message in the output window: 

[3392] w3wp.exe: Managed' has exited with code -4 (0xfffffffc).

If I return to my browser, my session has been terminated. If I immediately click on Debug>Attach to process and refresh the list, I can see that w3wp.exe (T-SQL, Managed, x86) is no longer in the list.

Can anyone help?

Cheers

James
