    Name resolution failing unless network adapter is re-installed


    Something is amiss with networking name resolution on my desktop PC. I frequently use Windows Explorer to access other Windows PCs on my home network, by computer name. I also occasionally use a VPN client on this PC. After disconnecting from the VPN client, I'll oftentimes no longer be able access the PCs by name--although the PCs can still be accessed by IP address.

    When this has happened, I've experimented with changing the settings in Network and Sharing Center > Advanced Sharing Settings, especially Network Discovery and File/Printer Sharing, one setting at a time, without success. Rebooting hasn't helped, either.

    My only resource has been to use Device Manager to remove (!) the Network Adapter (Intel(R) 82567LF-2 Gigabit Network Connection) and then perform Action > Scan for hardware changes. After performing this action, I can once again access the PCs by name.

    Any idea what is causing this ... and how to resolve it? FWIW, I never had this problem when Windows 7 was running on this PC.

    Local pcs dont use dns the use netbios it will take time for the netbio to see the pc and update once you leave a vpn you could try running from a admin cmd prompt NBTSTAT -R

    Thanks for the suggestion. It took this long (5 days) for the problem to occur again.

    I could not access PCs by name, even after 12 hours. Access by IP address worked.

    I ran NBTSTAT -R from an admin command prompt. The output was the standard "Successful purge and preload of the NBT Remote Cache Name Table"; afterwards, however, I still could not access the PCs by name.

    Like before, I removed the network adapter and then performed Action > Scan for hardware changes. I can once again access the PCs by name.

    Any other suggestions?

    The problem is still occurring -- in fact, it's now happening even though I've not been using the VPN client. I can still access PCs by IP address.

    What would cause name resolution to randomly stop working?!?

    The problem is still occurring.

    Would anything be gained by my performing a reset of Windows 10? Not sure what that all entails; I'd like to avoid having to re-install all of my apps.

    Thanks. I ran NetBScanner on the problem PC. It identified a few other devices on the network, including one that I frequently try to access (and am frequently unable to access, until I uninstall and re-install my NIC). Should I close the app and then simply run it again the next time I'm unable to access other devices?

    The master browser, according to NetBScanner, is running on one of the PCs I frequently access; i.e., it's not my primary desktop PC.
