Computers not seen on Microsoft network RRS feed

  • Question

  • This is a real strange situation: We have a local network of about 15 Windows 10 computers (desktops and laptops). When browsing the 'Network' via File Manager, we can see only 8 of them - the same 8 are seen everywhere. We can still access those that we don't see, by using their \\computer-name.

    There are many discussions on the web about the need to define the Function Discovery Resource Publication service as "Automatic" and restarting it. After playing a little with this service's properties in one of the "unseen" computers, including some playing with its "Log On" properties -- this computer suddenly became seen to all, but another computer (which was previously seen) became unseen to all.

    Any help or ideas?

  • Hi,

    It's weird. Have you checked following services on these computer?

    Here is a list of the services involved:

    http://msdn.microsoft.com/en-us/library/aa363906(v=VS.85).aspx

    • Computer Browser
    • SSDP Discovery
    • UPnP Device Host
    • Registry
    • Function Discovery Resource Publication
    • Function Discovery Provider host
    • Link-Layer Topology Mapper

    Make sure to check the Network discovery settings under Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settings

    Also, make sure the Network locations are same on these PCs: View your active networks

    Control Panel\Network and Internet\Network and Sharing Center

    In addition, what' the results if you turn off the Firewall for the computers which are not discovered.

    Please check if following ports are blocked by Firewall:

    • TCP 2869 – UPNP
    • TCP 5357 – WSDAPIEvents
    • TCP 5358 – WSDEvents Secure

  • Check if some Windows 10 machines are using PIN login or password login. If so, change to password login and you should see all computers.
