Windows 10: Can't access mapped network drive by name - "The specified network name is no longer available"

Hello, recently I'm having a hard time accessing a network mapped drive by name. Access by IP works just fine, by name rarely works, always gives us a error "The specified network name is no longer available".


I've managed to track down when it all started going wrong, and i it was after installing a update, Windows update KB4565503. No other drivers or software was installed, just the update. I've download every most recent driver from the manufacturers site and upgraded them. Didn't fixed anything


These computers are in a domain, which delivers the windows updates automatically, so, i don't really want to disable them. SMB is installed but i'm not sure if there is an issue with it


This looks like its a DNS problem, but if so, how is it possible that only some computers on this update are affected ?


Any help will be appreciated, thanks in advance

“The specified network name is no longer available”

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

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.
