  • User-1934530859 posted

    I have a web application that I run from my local IIS not Cassini. If I try to run in debug mode or if I even try to run the app from IIS it immediatly kills the app pool and gives me the following:

    HTTP Error 503. The service is unavailable.

    i don't see anything in the event log, what could be causing this?

    Hi,

    HTTP Error 503. The service is unavailable.

    You could have a try the method below, and check whether it is helpful to fix the error that “Service Unavailable: HTTP Error 503”

    1.Open the Internet Information Services (IIS) Manager

    2.Select the Application Pools node under the root node in the left hand side frame

    3.Right click on the DefaultAppPool. If the service is stopped, start it. If the service is running, restart it.

    At the same time you could also check EventLog to learn detailed information in C:\Windows\System32\LogFiles\HTTPERR folder,

    Troubleshooting 503 "service unavailable" errors

    hope it helps you,

    With regards

    Are you running different ASP.NET website versions on the same app pool?

    Try to give everyone rights to your website folder. Or check the app pool recycle code.
