=========<\/p>\n

Hello all-<\/p>\n

this is a follow-up to my original post <\/a>in which I discussed how to setup cross-subnet browsing so that all computers come up in “Network” or “Network Neighborhood”.<\/p>\n

For the last few months, my “Network” browse list has disappeared and would ONLY show computers from my LAN subnet.\u00a0 My remote (VPN-to-VPN) network subnet disappeared from my “Network” computer list.<\/p>\n

After >>MUCH<< research I have found the problem and will present the solution.<\/p>\n

The problem is due to the Microsoft Windows Update (for both desktop and server OS’s) KB3161949\u00a0 (read about it here<\/a>).<\/p>\n

Part of the effect of this update was to “harden” the NETBIOS service and prevent NETBIOS data from being sent between subnets.<\/p>\n

 <\/p>\n

THE SOLUTION:<\/strong><\/p>\n

Two ways of handling this.<\/p>\n

    \n
  1. You can remove this specific hotfix<\/li>\n
  2. You can add a registry setting to override it.<\/li>\n<\/ol>\n

    (YOUR CHOICE)<\/p>\n

    To REMOVE the hotfix:<\/p>\n

    On SERVERS<\/strong>:\u00a0 Go to Control Panel, Uninstall a program, View Installed Updates… Remove 3161949.\u00a0 You’ll need to reboot.\u00a0 After rebooting, go check for windows updates again (MANUALLY)\u00a0 3161949 will pop up.\u00a0 Right click and HIDE UPDATE.<\/p>\n

    On Desktops:\u00a0 Same process as above – HOWEVER – Depending on which version of windows, which OS Rollup you are on, 3161949 might not show up.\u00a0 If you cannot remove 3161949, simply add the registry key below.<\/p>\n

    –OPTIONAL METHOD–<\/p>\n

    Involves a registry key addition, then you need to reboot the machine.<\/p>\n

    SUBKEY:<\/span>\u00a0HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\NetBT\\Parameters<\/span>
    Value Name<\/span>: AllowNBToInternet<\/span>
    Type<\/span>: Dword<\/span>
    Value<\/span>: 1<\/span><\/p>\n

     <\/p>\n

    ** REMEMBER TO REBOOT after you do either the uninstall or registry key.<\/p>\n

    ** It will take 5-60 minutes for the Network browse lists to refresh<\/p>\n

    *** MOST IMPORTANT ***<\/p>\n

    You MUST do this on your domain servers (Master Browsers) on each side of the subnet.\u00a0 For example, I have for domain servers, two on each side.\u00a0 I did this procedure on both, then rebooted all four domain servers.<\/p>\n

    Then I did this on my Windows 10 Pro workstation (via registry key) and rebooted.<\/p>\n

    When I checked my computer 30 minutes later, all machines were showing up in the browse list under “Network” in Windows 10.<\/p>\n

    ** ADDITIONAL NOTE:\u00a0 Just for the heck of it, you might as while put that registry key onto all your domain servers.\u00a0 Even though I had uninstalled 3161949 from all 4 of my domain servers (and hidden that update), one of my DC’s re-applied that patch and rebooted, thereby messing up my Network list again.\u00a0 So I just went and put that reg key onto all 4 DC’s just in case they get that update somehow in the future.<\/p>\n

    ** NOTE: Do this at your own risk.\u00a0 I’m not responsible for your network security.\u00a0 You have to make the decision on what’s more important to you here.\u00a0 Being able to see the entire cross-subnet network, or security.\u00a0 I can’t speak as to how this increases or decreases your security risk.<\/p>\n
