Today’s one-liner is one that you or may not have to use a lot depending how your environment is setup and how you setup computers. Either way, its great to have it so you don’t have to go digging for it in the GUI. Ever had a time when you are trying to connect to a computer, and can’t? You make sure the computer is connected to the right wifi or that it is wired in, has the right IP address, and has internet… but nothing seems to work. Then you turn off your firewall and you can ping it… you know you can’t leave the firewall off all the time. What to do?
Set-NetFirewallRule -DisplayName "File and Printer Sharing (Echo Request - ICMPv4-In)" -Enabled TrueThere is your answer. That simple one line of code enables pinging without turning off your whole firewall. You can do this in group policy or add it to your golden image for imaging computers.
Hope this helps and saves time you prepping computers!
