    My problem is not the same as OP since I can connect to internet just fine, but since it's related to Treshold 2 update and networking I'll post this here anyway.

    Again, no such problems before the 1511 update. I first noticed, the problem only manifested itself if I used a static IP on my computer. Switching back, to obtain IP automatically, fixes it.

    Upon further investigation it seems this bug is related to NetBIOS over TCP/IP. If it's disabled, problem disappears. It seems it's enabled by deafault when using static IP.

    I also disabled LMHOSTS lookup but I don't think it's related to this. Hope this helps somebody.
    This was an issue that appeared prior to the Win 10 RTM, and was fixed in a further update prior to RTM. It appears the same bug, or a similar one, has cropped up again, and it's recommended to file a bug report with Microsoft directly.

    In regards to NetBIOS over TCP/IP, it should remain on disabled. NetBIOS is meant to be used on LANs, however if you do not disable it, it will attempt to connect to computers and servers in WAN on ports 137 - 139. Specific firewall rules should be in place to allow traffic on ports 137 - 139 and 445 within the LAN for SMB/CIFS shares

    Thank you for taking the time to try and help, however the issue you describe issue is not the same [nor similar] as the issue this thread is about. Also, the hotspot shielding you mention is specific to your wifi driver, or possibly your third party firewall/internet security program.

    This seems to be the problem that I am having, as my Network Connection Details indicates that NetBIOS over TCP/IP is enabled. However, I can't figure out how to get to the above Advanced TCP/IP Settings window. Any help doing that would be greatly appreciated.

    The issue is not caused by NetBIOS over TCP/IP being enabled, disabled, or set to default; the issue is caused by a permissions issue, which should be obvious from the error that's received. For some reason, Windows believes a specific group policy has been enabled even though it hasn't; the most likely cause of the issue resides within the registry.

    NetBIOS over TCP/IP should be disabled unless your PC connects to a corporate network, or you have set up your home network in such a way that it needs to be enabled. When NetBIOS over TCP/IP is enabled, it sends out UDP packets continuously to WAN. To disable NetBIOS:

    1. Control Panel - Network and Internet - Network Connections
    2. Right click the adapter and select Properties
    3. Highlight IP v4 (TCP/IP) and select Properties
    4. Select Advanced
    5. Select WINS tab, tick Disable, and select OK all the way out

    You are right. I disabled NetBIOS over TCP/IP and it didn't help. However, I have reinstalled the WiFi driver, and now the troubleshooter says 'The DNS server isn't responding. Your computer is trying to use a DNS server that is incorrect or doesn't exist.' So, I have moved over to that thread to try to resolve the issue.

    Thank you for your prompt reply.

    Make sure you install latest official Wi-Fi driver from manufacturer, not from notebook's support site (usually outdated) or from Windows Update. Use a utility such as Aida64 to see the exact model. No need to register, the trial version should be OK. For Atheros you can look at the unofficial Atheros drivers site. For anything else, Google to find manufacturer's site.

    Thank you very much for posting this. I can't tell you how many hours I have spend looking at forums and trying things. I knew it was permissions related, but would never have found these settings or know what to change. Now I can get to some vital files shared on a server.

    NetBIOS being enabled or disabled wouldn't have prevented you from accessing network shares.... nor does NetBIOS have anything to do with the error received when trying to install/reinstall network protocols.

    Thanks for the link to the Atheros driver site. I did get an updated driver, however, it didn't help my problem. Thanks for replying, though.
