.Synopsis
Script checks if any of the Store and Forward (SAF) machine services are stopped. If any(or all) of the services are not running, it will manually stop, then start all the services and check the services again to see if they are running. 
The script loops through this check 3 times before exiting.

.Modified

2024-02-05 (CraigK) - Removed code in start \ stop functions that wasn't needed
2024-02-06 (GabeK) - Updated script with loop function
2024-02-07 (GabeK) - updated script to remove verbose and added output of stopped services
