Enable RDP and Samba / Shares in Windows 10 Firewall

If connections to RDP or Samba shares to a Windows 10 machine fails you may check the firefall configuration on the client.

Click on "Start" und type "firewall". Navigate to "Windows Defender Firewall mit erweiterter Sicherheit" (extended security).

A window opens. Navigate to "Eingehende Regeln" (incoming rules) in the tree on the right side.

Enable the following rules for the "Domäne" (domain) profile (3rd colun):

• Datei- und Druckerfreigabe (NB-Sitzung eingehend), Protokoll TCP, Port 139
• Datei- und Druckerfreigabe (SMB eingehend), Protokoll TCP, Port 445 
• Remotedesktop - Benutzermodus (TCP eingehend)

Of course the corresponding functions have to be enabled and configured properly.
