Recently I was (re)setting up IIS from scratch on my development machine and kept getting HTTP Error 503 whenever I would try to load up a local web page.

For reference, in my case it's IIS version 8.5, running on Windows 8.1 Enterprise 64-Bit, but that really shouldn't matter.

Looking in the Windows Event Viewer shows:

  • Application pool '<app pool name>' is being automatically disabled due to a series of failures in the process(es) serving that application pool.
  • The Windows Process Activation Service failed to create a worker process for the application pool '<app pool name>'. The data field contains the error number.

Before losing any more hair, and/or trying anything else, give this a try, it worked for me:


  1. Go to the Application Pool ...

  2. Advanced Settings ...

  3. Process Model ...

  4. Identity ...

  5. Set it to "LocalSystem"


You may or may not need to Restart the Application pool/Server afterward, but it's always a good idea anyway.
