Website under IIS 7.5 with Application Pool giving Server Error

I created a new application pool in IIS 7.5 and chose ApplicationPoolIdentity for Identity.

When I assign a website to use this app pool, I get a 500 server error. I have other websites using application pool with same Identity and asp.net runtime and get no error.

I changed Identity on the pool to NetworkService, LocalService, LocalSystem and still get the same error.

Why am I getting this error, and how can I overcome this?

Thanks in advance.

Is the website code the same? The 500 Internal error is not always related to IIS problems. – Taicho
yes, the content is the same. I only change the application pool that the website uses and I get or not get the error based on which pool is used. – IIS7 Rewrite

It would be helpful if you posted the error you are getting. If you have other applications using this app pool, and they are working, then I would be suspect of the application, or the applications dependencies/references. If this is coming from a previous version of iis that ran in 32 bit mode, you may need to enable 32 bit mode in the application pools advanced options. Post the text from the exception and we could provide more precise troubleshooting steps.
