Welcome all, to the age of the gui-less windows server. As more and more people spin up labs with command-line only boxes, this command can be helpful.
Remember to only turn off your firewall in lab environments where you know you’re not exposing yourself to additional risk.
Set-NetFirewallProfile -Profile Domain,Public,Private -Enabled False
To do this using netsh in cmd, you can use the following command.
netsh advfirewall set allprofiles state off
I hope this makes your day at least a little bit easier.
