    “The specified network name is no longer available”


    I have six systems in my home, five running Windows 10 with the Anniversary update and a sixth that just won’t take it yet, and is stuck with the original Win 10.

    All of these are somewhat networked together, along with several more that are not in our home. (I use Hamachi to connect these.) The home systems are ALSO linked to shared storage off the Linksys router.

    Recently, my Qosmio 870 developed amnesia when it came to Cortana. Nothing I tried would recover the search engine. Today I tried re-installing Windows 10 Pro from the most current installation download.

    Cortana is back in full bloom, and aside for those pesky shortcut arrows returning, all seemed right with the world…

    Except!! My router-shared storage is unreachable. I can no longer map to the router. I attempt mapping (\\RouterName\Sharestorage) and get … “The specified network name is no longer available”. All the other systems are fine and I AM online to/with my router.

    I reverted the system to “Before the update”, and all is well with the router, but of course I don’t have Cortana.

    I’d welcome any advice anyone might offer. I’m not sure what to try next.

    Thanks.

    Have you tried using the IP address UNC syntax? It just tried it on my network and was able to type

    net use \\192.168.0.2\<sharename>

    and immediately got access that way. If you're having trouble with name resolution maybe you can use the IP address instead.

    For a Windows 10 PC to be able to see a UNC resource of the form \\<device name>\<share name> then both devices should be in the same Workgroup and Network Discovery should be turned on. It may well be that when you reinstalled Windows 10 it was set to a default Workgroup name different from that of your router.

    My router came pre-configured with a Workgroup of HOME. There are no user settings to change this, so all PC on my network (W10, W7, XP and on rare occasions W95) have to be set to be in the HOME Workgroup. They can all see each other's shares and a USB HDD shared by plugging it into the USB port on my router.

    To check/change the Workgroup of a W10 system, go to Control Panel\All Control Panel Items\System and click 'Advanced system settings' (or just type Workgroup in the Search box). Look on the 'Computer name' tab.

    For Network Discovery settings, go to Control Panel\All Control Panel Items\Network and Sharing Centre\Advanced sharing settings

    Sounds like the Router needs to be turned off and back on to clear its temporary storing of the network info, same as the devices need to have the cache, etc. cleared to flush out old information.

    So I (and a lot more users) are stil left SUFFERING from this crazy error. I also have some very strange issues with the NVidia 373.06 WHQL drivers. NO, these late updates DON'T JUST WORK!!! /rant

    Overall very disappointed in these latest flaws in M$ updates/grades!

    RESOLVED my network issue!


    FWIW to others users: RESOLVED my network issue!

    It seems that the latest AE 1607 build and updates KILLED my bridge (2 GB/s) of 2 NIC's in my Mac Pro. Deleted the bridge, disabled 1/2 NIC's in Device Manager and set up a new WLAN:

    Tried that. No joy. Thanks for trying, however.

    Are you sure you have the right IP address for the remote device with the shared resource? In my experience if you haven't changed the default address, it's 192.168.0.1 for most routers (but sometimes 192.168.1.1). Get yourself an IP scanning utility and confirm that the address is correct, or run ipconfig and use the address for the "default gateway" as shown here:
    -defgate.jpg
    The address I gave you was just an example (it's actually the address from my wife's PC on my LAN, to which I navigated to make sure the syntax was correct and acceptable to Windows 10).

    Ed,

    This gets curiouser and curiouser! The default gateway is 192.168.1.1. I CANNOT connect using that IP and the latest update. I reverted to my previous Win 10 build and can easily connect using the IP rather than the \\Shamrock-2. Of course, there’s no Cortana. I'm missing something somewhere.
