The WWW Publishing Service was unable to successfully start a worker process.
This issue could be attributed to any of the following problems:
worker process identity is incorrect.
Insufficient memory to start another process
Too many concurrent worker processes running.
Ensure that the identity of the application pool is correct and is added to the IIS_WPG group. Also, verify that the server is not constrained to memory resources and can launch another process.
