Where can I find Application ID for website in IIS 6?
Open IIS manager, click on the top level websites folder, view the lists of sites in the right hand pane, listing the App ID's.
Or, you can open up a command prompt (Start --> Run --> 'cmd') and type in: iisapp
That will give you a list of sites currently running, the PID of the process and the App ID you need.
You can open run a command window then type
isapp.vbs. It will list all websites with id.
