    Network computers not showing after 20H2 update


    All,
    There seems to be a problem with the network computers not showing up.
    Say my computer is named "BRYCE-PC" and the remote computer is "YuleLog-PC"
    I am trying to get psexec to work properly, and worked until today.
    I have Spectrum (using their new Wave 2 router and Modem with QR Code) and resetting it shows the computer for a split second, and then disappears.

    The above picture shows what it does now.
    The below picture shows what I try to do in order to connect.

    I have enabled Function Discovery and placed on Autostart, already have everything on except password, and reset modem and router, only to work for a few seconds.

    And also it seems to be RDC is broken too

    In my case, updates reset the share settings.
    Check that your advanced sharing settings under "All Networks" has the sharing turned on.

    Try to connect using the computers IP in file Explorer
    EG:
    Code:
    \\192.168.x.x
    This will show you all the shared folders on that computer and if you right click on a folder you can select "Map Network Drive"

    For some reason Windows prefers the IP compared to the computer name, Probably due too not being able to pick up the IP from your DNS server which is usually your router or not reading the ARP table from itself.

    Yep. It seems Sharing is turned on. I'm not sure why updates change that setting in my case. It happens with every major update.

    Also, something I've noticed when trying to troubleshoot these kinds of problem is sometimes the changes you make to correct the problem don't have an immediate affect. They take time to propagate through the network or take effect after the PC you changed or other PCs on the network are rebooted. This makes it really hard to know what change actually fixed the problem. One day you'll just start seeing the computer on the network and have no real idea which change actually fixed it. You'll just assume it was the last thing you did. I think this is why there's so much misinformation out there on this subject. Everyone claims the last thing they changed fixed the problem for them.

    Ok.

    I will try to reset the computer and downgrade to 2004. If that works then it seems to be a bug!

    Try this this. I had a similar problem.

    On all affected machines, set these values in Programs and Features. May need a restart.
