Start, Stop & Restart IIS 7.0 on Server (Complete Guide)

hen you shut down an Application Pool in IIS 7.0, all running worker processes using that pool stop because the Windows Process Activation Service (WAS) also stops. As a result, you must manually restart these worker processes after the WAS restarts. Otherwise, if you attempt to access any applications routed to the application pool without restarting the worker processes, you may encounter an error such as “503 Service Unavailable.” Therefore, ensure that you restart all necessary processes to avoid downtime.

How to Start or Stop the IIS 7.0 Management Service:
The IIS Manager does not start the management services by default when accessing it. Server administrators need to start them to enable:
