Hi,
I am working on an ASP.NET application which I am wanting to host on my SBS 2011 box.  It works fine under Visual Studio and the version of IIS that is provided by VS.  I have created a folder for the application called Dashboard in the following folder on the server:

C:\inetpub\wwwroot\Dashboard

I have created the Dashboard folder as an Application that appears under "Default Web Site" in IIS 7.0.
I have created an application pool called "Kohola Dashboard" and assigned the "Dashboard" application to it.

The application uses Dot Net 4.0 and is an x86 32 bit application, it also uses OleDB to store its data in an Access 2003 compatible database. In the application pool advanced settings I have set the "Enable 32 bit Applications" to true and selected .NET Framework version to v4.0. The pipeline mode to Integrated and used a user called "IUser" as the Identity and I have ensured that user does exist and does have permissions to read and write to the C:\inetpub\wwwroot\Dashboard folder and its subfolders.

When I try to connect to it there is a slight delay and then I get an Error 503 and when I check the application pool it says the status is stopped.  Checking the server's System Event logs I am getting a stream of errors like this:

Event 5139 WAS:
A listener channel for protocol 'http' in worker process '11680' serving application pool 'Kohola Dashboard' reported a listener channel failure.  The data field contains the error number.

Event 5139 WAS:
A listener channel for protocol 'http' in worker process '9768' serving application pool 'Kohola Dashboard' reported a listener channel failure.  The data field contains the error number.

Event 5139 WAS:
A listener channel for protocol 'http' in worker process '11740' serving application pool 'Kohola Dashboard' reported a listener channel failure.  The data field contains the error number.

Event 5002 WAS:
Application pool 'Kohola Dashboard' is being automatically disabled due to a series of failures in the process(es) serving that application pool.

Can anyone help with what is causing this and how to stop it from falling over?
