    mmc.exe Network Traffic? Should I Allow?


    Hello,I got the notification that Windows Defender Firewall blocked mmc.exe while in Component Services and Event Viewer. Why is mmc.exe utilizing the network? Should I allow? Could this be used to harm my system? mmc.exe just views items and doesn't change settings?Windows version 21H1 19043.1165

    :)

    Monitoring incoming and outgoing network traffic separately?

    You would only see all network traffic not what enters/exits the WAN port on your Modem/Gateway for a particular IP on the LAN. You would need to forward all traffic through either a Proxy on the network or use pfSense as your Gateway. Now there are routers like the ASUS that use Merlin’s firmware, which allows you to see per ziP and all traffic through the WAN port.

    Microsoft Defender firewall list of allowed apps and functions

    The "list of allowed apps" refers to inbound connections, not outbound.

    Inbound connections for LoL game would be blocked ex. if you host your game server, however to play multplayer games this is all about outbound traffic which is by default allowed.

    KB4524147 / Startmenü / HP NetworkPrinters / unknown Network Traffic

    Hello Microsoft,

    • Printers
      • We have recived several reports from Companies we support about Issues with their Printer. From a close look all affected Companies are using HP MFPs. The Networks we provide with "other" MFP Suppliers are not affected. Our Solutions was to remove the KB4524147
        and restart the Clients.
    • StartMenue
      • Some Devices have fatal Startmenue failure. This could be solved by your Artikel given on another
        support request. The Issue here is that we have on several Companies different AP types. One for example has standart Desktops like: Desktop --> ASUS H310M-A R2.0 ; Intel Core i7 ; 8 GB RAM Windows 10 Professional. All Client AP are sset up with the same Update
        Level. Only a few devices have the Starmenue failure.
    • unknown Network Traffic
      • some Devices on another customer Network has started a significant raise of unknown Network Traffic. It did not caused any harm yet as our Firewall has recognized it and is now reporting every minute since then about this. The User is not complaining of
        any "change" on his Device? And also we figured out that remopving the KB4524147 stopps the network traffic. Reinstalling it causes it again. Again its on similar APs with same Setup like: Gigabyte Brix (mini PC) --> Intel Core i5, 8GB RAM / Windows 10 Pro.
        We are investigating still the cause. Could be coincidenc...
    Please let us now what kind of Data or Information you need to solve the Printer and StartMenue issue.

    Please let us know if any other report is known about this "unkown network traffic" from your sides.

    Thank you and best regards
