Machine key encryption can be set by using the UI, running appcmd.exe commands, by editing configuration files directly, or by writing WMI scripts. To set the Machine Key encryption at the global level using an appcmd.exe command: %systemroot%\system32\inetsrv\appcmd set config /commit:WEBROOT /section:machineKey /validation:SHA1 Note: When Appcmd.exe is used to configure the <machineKey> element at the global level in IIS, the /commit:WEBROOT switch must be included so that configuration changes are made to the root web.config file instead of ApplicationHost.config.
