ASP.NET 2.0 files work in one folder, but NOT in another

I have created an ASP.NET application for a client and all the files are in a folder on their D drive.

Now it is time to go production, so I copied all my files and folders to their existing classic ASP folder on the same drive.

When I browse to the application it fails to launch.

The only difference I can see is that the development site does not require HTTPS like the production site.

I also made sure all the permissions are the same on both folders. I also made sure that the GAC has read rights using the aspnet_regiis tool.

I am at the end of my debug knowledge, could someone please help me out.

Here are the error messages I get from the application event log.

Failed to initialize the AppDomain:/LM/W3SVC/3/Root

Thank you for your help,

Some things worth checking:

• Folder permissions to ensure that the IIS worker process has access to the folder the files are in
• If the files are in a folder - that the folder is set up as a virtual directory in IIS and you have clicked the create button in the IIS control panel to create an application.

Have you made sure the worker process account is configured properly. Try running the following in the C:\Windows\Microsoft.NET\Framework\v2.0.50727 folder:

aspnet_regiis -ga <worker_process_account_name>

Thank you everybody for all you suggestions and help. Since nothing worked and made no sense to me I decided to reinstall the framework and everything is fine now.
