I am being asked to resurrect a classic ASP application for temporary use. Wonderful. Well, the pay's the same, so I am now trying to get the thing to run on my localhost so I can test it and so on. I have copied all the files to c:\inetpub\wwwroot\ClassicASPapp. Using IIS 7.5 I set this folder as an Application I get handed a 503. Same result if I make it a Virtual Directory.

HTTP Error 503. The service is unavailable.

Note that there is a file in wwwroot called "iisstart.htm". If I double-click on the file from Windows Explorer, the browser displays the rendered HTML correctly. If I try to navigate to the file using:

http://localhost/iisstart.htm

I get the 503 then, too.

What is going on? Is there some global setting I need to change? Note that this is a new Windows 7 workstation.

I've checked and Classic ASP is definitely installed. The web site is associated with an application pool that has Classic ASP enabled, and 32-bit applications are also enabled.

It is true that the application pool gets stopped.

Test Connection / Authorization Detail:

The server is configured to use pass-through authentication with a built-in account to access the specified physical path. However, IIS Manager cannot verify whether the built-in account has access. Make sure that the application pool identity has Read access to the physical path. If this server is joined to a domain, and the application pool identity is NetworkService or LocalSystem, verify that \$ has Read access to the physical path. Then test these settings again.

  • Did you see anything interesting in the Event Log? Whenever you see a 5XX error, there is usually some info logged. – Nitz Aug 8 '14 at 21:01
  • Well, @Nitz, I don't know if it's interesting, but I've added an entry I found in the Log. – Cyberherbalist Aug 8 '14 at 21:50
  • This event is a good clue. Look for events happening a tiny bit earlier indicating the "series of failures". My money is on the login - is it using an application pool with a specific user (not the default identity)? – Nitz Aug 8 '14 at 21:55
  • There is a series, but all of them say "The Windows Process Activation Service failed to create a worker process for the application pool 'DefaultAppPool'. The data field contains the error number." I don't see a "data field". – Cyberherbalist Aug 8 '14 at 22:15
  • Try looking for events in logs "Application" and "Security" – Nitz Aug 8 '14 at 22:22
