Windows 10: Network discovery not working

Solved
ILV -  
 ILV -

Hello,

I have created a home local network with several machines running W10 to share resources.

But on one of them, I can't activate network discovery: when I go to "Network and Sharing Center / Advanced sharing settings," I click on "Turn on network discovery," but when I save the changes, the setting automatically reverts to "Turn off network discovery."

I checked the network adapter settings, everything is fine. I even reinstalled Windows to restore the default service configuration. Nothing works. I'm stuck...

Thank you for your help ????

    Problem solved!

    By following each step of this tutorial: https://www.malekal.com/decouverte-reseau-fonctionne-pas-windows-10-11/

    It was the resetting of Winsock and the TCP/IP stack that allowed the "Function Discovery Resource Publication" service to start and consequently I was able to enable network discovery.

    Thank you all for your help!

      Weird,

      if you reinstalled Windows, you normally don't need to reset the tcpip stack, it should be in place.

        Yes, I admit my limitations in understanding the problem; perhaps resetting winsock helped. I don't have a grasp on it... but the result is there.

    Hello,

    start by checking that you're on a private network, not a public network.

    And there you go ....

    But for heaven's sake, those line spacings are so annoying!!

    Yes, I confirm, private network and logged in as administrator.

      Otherwise, is the network working?

      Internet access and access to Windows shares, the ping first?

      The internet access works when I connect to the box via wifi.

      But when I change networks and return to my private network (still via wifi), the computer does not appear on the network.

      Sharing is enabled, but since network discovery is not functioning, there is no way to access it.

      As for the ping, it goes from a computer on the network to this one, but not in the other direction. The machine only pings the router...

      The router ...

      Do you have a router in addition to your box?

      A ping that only goes one way is always a firewall problem, or a NAT router between the two, which is pretty much the same thing.

      Network discovery is not useful for exchanges via SMB; you should be able to connect to a network share on the other machine even without it appearing in the discovery by the UNC path:

      \\ip address\share name, then the appropriate user account.

      Network discovery is net view

      https://superuser.com/questions/361277/explain-windows-net-view-command-switches

      net view ip address

      In fact, discovery encompasses several protocols in parallel, from lldp to nbt (netbios) through ssdp and other dlna, it all depends on what we are looking for and especially what we announce; I’m giving you these keywords if you want to know more.

    After some research on the Microsoft forums, I found an identical problem but for a Windows Server 2012.

    I restarted the necessary services but there is one that resists me: Function Discovery Resource Publication.

    And still no network discovery possible ????

    I click on "enable network discovery" but when I save the changes, the setting automatically reverts to "disable network discovery."

    Hi

    ??? If you have enabled network discovery, it's normal for the option to disable it to be presented to you afterward.

    Otherwise, is SMBV1 enabled?

      Hello,

      the option to disable is not offered, it is checked when I return to the page to verify if the changes have been taken into account. So the previous validation had no effect.

      Smbv1, no, not activated.

      Hello,

      what is SMB V1 used for?

      In principle, it does not participate in discovery.

    Is this key in Regedit like this?

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters\Internet]
    "EnableActiveProbing"=dword:00000001
