To complete these procedures, you must be a member of the Domain Administrators group, or otherwise be delegated permissions to modify the GPOs.

To configure the Windows Firewall log Open the Group Policy Management Console to Windows Firewall with Advanced Security (found in Local Computer Policy > Computer Configuration > Windows Settings > Security Settings > Windows Firewall with Advanced Security).

• For each network location type (Domain, Private, Public), perform the following steps:
  
• Click the tab that corresponds to the network location type.
  
• Under Logging, click Customise.
  

The default path for the log is %windir%system32logfilesirewallpfirewall.log. If you want to change this, clear the "Not configured" check box and type the path to the new location, or click "Browse" to select a file location.Important: The location you specify must have permissions assigned that permit the Windows Firewall service to write to the log file. The default maximum file size for the log is 4,096 kilobytes (KB). If you want to change this, clear the Not configured check box, and type in the new size in KB, or use the up and down arrows to select a size. The file will not grow beyond this size; when the limit is reached, old log entries are deleted to make room for the newly created ones.

No logging occurs until you set one of following two options:
To create a log entry when Windows Firewall drops an incoming network packet, change "Log dropped packets" to "Yes."
To create a log entry when Windows Firewall allows an inbound connection, change "Log successful connections" to "Yes."
