After rebooting Windows 2012 with IIS8 installed running in a shared config.
The Module DLL C:\Windows\System32\inetsrv\iis_ssi.dll failed to load.
The data is the error.
After adding the server side include feature again it works, until the next reboot. I hope there is another answer besides a re-install of IIS.
Option 1)dont allow automatic reboot
Error Message: Feature installation. The request to add or remove features on the specified server failed. The operation cannot be completed, because the server you specified requires a restart.
Option 2)allow automatic reboot; also stopped www service
Error Message: The request to add or removed features on the specified server failed. Installation of one or more roles, role services, or features failed. Error 0x800f0922
