How to troubleshoot an IIS "Event ID: 1009" error.
An error that most IIS 6.0 administrators have probably encountered is "Event ID: 1009" which usually leads to a "503 Service Unavailable" error being displayed in a browser. "503" usually indicates the Application Pool has been disabled for some reason. The IIS support team frequently gets support calls to help resolve this issue and over the years I have compiled a list of steps I use to troubleshoot this. If the following information seems too confusing please let me know and I'll clarify any confusing points. The follow list is broken down into different sections for the various "exit codes" that are in the Event 1009.
