HTTP Error 404. The requested resource is not found- Exchange 2013

Just received error when i was trying to access Exchange 2013 ECP: https://tech/ECP
HTTP Error 404. The requested resource is not found.


First I checked IIS services as per my suspect and found WWW publishing service was not running and Windows process activation service also not running. I tried to start the services but received below error:

All other windows process activation service dependencies was also not running:

Another error when i opened IIS


After lot of research found applicationHost.config was corrupted, for resolve the issue need to  replace the applicationHost.config file located in c:\windows\system32\inetsrv\config with a backup file which is located in c:\windows\system32\inetsrv\config\backup\IISBackup.

Hope this troubleshooting will help you resolve the issues.
