This happened when we migrated our applications to new servers. This is a known IIS bug. You will have to uninstall IIS, reinstall it, and then delete pagefile.sys (windows will automatically recreate it, so don't worry).

Also make sure that these IIS extensions are installed and activated correctly.


Hope this will resolve all your problems.
