    Windows 10 is sending multicast ssdp packets, on what purpose they are used and how to stop them? I have ssdp and upnp services disabled. From wireshark.

    ST: urn:dial-multiscreen-org:service:dial:1\r\n
    USER-AGENT: Microsoft Edge/85.0.564.70 Windows\r\n
    [Full request URI: http://239.255.255.250:1900*]

    It looks like it's from Edge...

    SSDP Discovery missing from Services.msc

    Hi Expert,

    Is there anyone could explain why the SSDP discovery service is missing from my WIN7 computer?

    I am trying to turn on the network discovery, but it sees didn't work, then I following the Microsoft KB suggestions to start the below services:

    • DNS Client
    • Function Discovery Resource Publication
    • SSDP Discovery
    • UPnP Device Host
    when I trying to start SSDP Discovery, I found the service is just missing from my computer, I got no idea about that.

    I checked in HKLM\SYSTEM\CurrentControlset\Services\， no any key about the SSDP discovery service, then I export the KEY from one normal WIN7 PC, import to the one which got network discovery issue. But seems it's not working, I still cannot find the SSDP
    Discovery service in services.msc.

    I have google so many troubleshooting, none of them worked for me. Please suggest,thanks!

    Windows 10 randomly stops SSDP Discovery service

    Hello Everyone,

    Windows 10 1909 is stopping the SSDP Discovery service at random intervals, even if the service startup type is set to Automatic. This effectively makes my PC invisible to other PCs on the network.

    The only way I've found around this problem is

    1. Access Windows Services
    2. Find the the SSDP Discovery service. It will not be running.
    3. Restart the SSDP service. Ensure that the startup type is still set to Automatic. The PC is now visible on the network.
    4. Some time later, Windows 10 will arbitrarily stop SSDP Discovery again, and the PC will not be visible on the network. I repeat steps 1-3 to get it running again.

    Why does Windows 10 do this? Do I have to keep re-starting the service this way in order to keep my PC visible on the network?

    Thanks for your time,
