    Migration af Umbraco to IIS7

    Hi everyone,

    I have taken over an Umbraco installation from a previous coworker. The server hosting the application must be shut down and therefore I'm migrating the application to a new server.

    The old server is running IIS6, but the the new server is running IIS7. When I try to open the site on the new server, I get a "Object reference not set to an instance of an object" exception. The YSOD does not provide much info on what's going wrong (see below). 

    When I run the application locally in Visual Studio it works like a charm. Do any of you have a clue to what is going wrong?

    The application is coming from a IIS6, so I set it to run in classic mode. I tried changing to integrated but I get the same error. 

    It is running under NetworkService. The other applications (not Umbraco) are set up the same way and they run fine. 

    BR,

    Steffen,

    Open the app pool in iis7 and change the user its running under to application identity. Then change the version to .net4 integrated. See if that fixes it.

    Do you mean the user ApplicationPoolIdentity?

    I tried all the users in the dropdown (LocalService, LocalSystem, NetworkService and ApplicationPoolIdentity), but none of them work.

    Best regards,

    Steffen
