3. PowerShell command to Edit/Enable the Predefined rule in Windows Firewall

Run the PowerShell command to Edit/Enable the Predefined rule in Windows Firewall for File and Printer Sharing Group.

This is a bit tricky as there are two parts to it. When we already have Windows Firewall rules for the File and Printer sharing group, we can run the following command to enable those rules. The second part is covered in point #4. For SCCM/ConfigMgr 2012 client, we need to allow the Inbound and Outbound Firewall rules for all the predefined ones under File and Printer Sharing group.

Get-NetFirewallRule -DisplayGroup "File and Printer Sharing" -Direction Outbound | Set-NetFirewallRule -Enabled True -Direction Outbound

All the Firewall Rules related to File and Printer Sharing are disabled 

Run the following Powershell command to LIST and enable already created rules under File and Printer Sharing

LIST Command:- (Get-NetFirewallRule -DisplayGroup “File and Printer Sharing” -Direction Outbound).DisplayName

To Enable:- Get-NetFirewallRule -DisplayGroup “File and Printer Sharing” -Direction Outbound | Set-NetFirewallRule -Enabled True -Direction Outbound

 Rules under the File and Printer sharing group has been enabled now

 4. PowerShell command to create a predefined rule in Windows Firewall

When there are no Predefined firewall rules present in the Windows Firewall console, then we can’t use the SET-NetFirewallRule PowerShell command. Rather we should use New-NetFirewallRule to create a new predefined rule in Windows Firewall console.

Powershell command:- New-NetFirewallRule -DisplayName “File and Printer Sharing (NB-Datagram-Out)” -group “File and Printer Sharing” -Enabled True -Protocol udp -RemotePort 138 -Direction Outbound

File and Printer Sharing (NB-Datagram-Out) rule has been created. Result screenshot after running the Powershell as mentioned above command.
