You can create a custom action using RDK to run iisreset.exe with its input parameters (drop down list):
/RESTART
This option stops, and then restarts all running Internet services.
/START
This will start all Internet services that are set to autostart.
/STOP
This will stop all running Internet services.
/REBOOT
This parameter will restart the computer.
/REBOOTONERROR
This restarts the computer only when an error occurs when trying to start, stop, or restart the Internet services.
/NOFORCE
Do not shut down Internet services on failure to stop them gracefully.
/TIMEOUT:val
This allows you to specify the timeout value in seconds waiting for a successful stop of Internet services. On expiration of this timeout, the computer can be restarted if the /REBOOTONERROR parameter is specified. The default value is 20 seconds for restart, 60 seconds for stop.
/STATUS
This displays the status of all Internet services.
/ENABLE
This enables the Restart API for Internet services.
/DISABLE
This will disable the Restart API for Internet services.
