I made a CompanySite website in IIS - it's the only website on that server.
I created .NET 4 Integrated pool for that website.
I've installed ASP.Net site into CompanySite and it works fine.
Now I'd like to install an application within this site. I create another .NET 4 application pool for that application. Then I install application into CompanySite using that application pool.
As soon as setup starts off the website goes offline either with 503 or with The page cannot be displayed because an internal server error has occurred.
The only way to fix this (that I have found) is to uninstall that application and restart Windows Server, not just IIS server.
Question is how can I install multiple applications within a single site?
