5106: WAS application modify failed

The IIS World Wide Web Publishing Service is responsible for managing the HTTP protocol and HTTP performance counters. An IIS web site is a unique collection of web pages and web applications that is hosted on an IIS web server.

Event 5106 is generated when the Windows Process Activation Service failed to modify an application in a site. The application and site are specified in the message. 

How could you resolve this situation?

Stop and restart the World Wide Web Publishing Service. This will also stop any other services that depend on it. So, they would also need to be restarted.
