Although Not complete solution, But I got some clues : http://support.microsoft.com/kb/329291[^] http://geekswithblogs.net/TimH/archive/2005/10/05/56029.aspx[^] http://forums.codecharge.com/posts.php?post_id=67135[^] All of the above post states that if application is trying to write to Event Log then is gives such exception. However :confused: You are saying there is no code in application. Still digging. :sigh:

Looks like your are using some session settings in web.config, and that is trying to access machine key for encrypting session data (Although not sure).

My concern is when DAC is singleton, single instance will be shared across all the session.

This depends if DAC is running in separate Application Domain and serving to multiple application instance via Web Service or any other interoperability methodology. Otherwise every application will have associated DAC running in same application domain, No matter how it is implemented.

I am totally confused how it will share the single instance across all the session. If the single instance serve each user request sequentially one after other, application will become slow, or mybe i am thinking completely wrong way.

You can easily figure out if DAC is running in separate instance by inspecting application architecture.

I am not able to get clue about, which kind of application you are working on. If you are developing Window Forms application then you can use SharpDevelop Form Designer[^] for this purpose, Alternatively if you are working on ASP.NET then you have to try some commercial tool kits :)
