Powershell: Enable Firewall Log

We sometimes need to enable Windows firewall's log to troubleshoot. Here is how.

Check current firewall's settings

Get-NetFirewallProfile

Enable logging blocked connections for Domain profile

Set-NetFirewallProfile -Name Domain -LogBlocked True

Verify settings

Get-NetFirewallProfile -Name Domain

Check the firewall log at %systemroot%\system32\LogFiles\Firewall\pfirewall.log. Remember to run as Administrator.

PS C:\WINDOWS\system32> Get-Content c:\windows\system32\LogFiles\Firewall\pfirewall.log
