Monitoring a PING connection with PowerShell

This script will let you silently monitor a PING connection to 3 hosts. We apply this via GPO as a login script and it will monitor the user’s connection to those hosts and write connection losses to the outfile shown in line 4.

If a connection loss to one of the main hosts occurs we added 2 subhosts to check and see if the connection to the local gateway and filesever is OK.
