NET framework 2.0 and IIS 6.0 problems: Faulting application w3wp.exe

Hello Experts:

I'm developing ASP.NET pages under IIS 6.0 om a Windows 2003 server. As long as I used the .NET framework provided with the server (1.4) everything worked fine. Recently I installed 2.0 Framework. Pages seem to work fine, but I got this persistent error in the application log

Faulting application w3wp.exe, version 6.0.3790.1830, stamp 42435be1, faulting module webengine.dll, version 2.0.50727.42, stamp 4333eca4, debug? 0, fault address 0x00002fec.

The Event id is 1000
The source is .NET runtime 2.0 error

I never got this error under 1.4, although web pages seem ok I am very concerned about it.

Any Ideas?

What is the Idle timeout setting under  Performance in the properties of the application pool ?

Is there any other error in the system longs related to this

Most probably the error may be due to unhandled exceptions in your code since earlier versions, the Microsoft .NET Framework 1.1 and in the Microsoft .NET Framework 1.0, unhandled exceptions on managed threads were ignored.

In one App, the Idle timeout is 120.

¿Is that the key?

can you try change to this in Aspnet.config file that is located in the following folder:

        <legacyUnhandledExceptionPolicy enabled="true" />

take a backup of Aspnet.config and keep it so that you can revert back to the old one if the solution is not working

Dear Dnojcd:

Thanks for your answer, but that is not the response I was searching for. As I am concerned when you set that propery to "true" what you are doing is just ignore these errors. I'd rather fix'em than ignore'em.

Yesterday I contacted Microsoft, they are lookin at the problem to see what it is.

I'll keep you informed about  their veredict at this post.

They have already answered.

Literally they have told me its caused by "a known issue they have been detecting in 2.0 Framework" (sounds like a bug). They have given me some hints about what to do next (i.e. deleting temp files in the framwork). I'll let you know if this solves the problem.
