networking - Windows 10 Pro Cannot UNC to network shares


I have a new surface book pro with Windows 10 Pro.
On this machine alone I am unable to access my network shares. I have several other machines on my network that can access these shares without issues.
Some shares allow anonymous access, others require credentials.


My shares are all on a synology rackstation.


When I attempt to access my shares via UNC in explorer I receive an



unspecified error



Attempting to create a mapped drive via CMD shows error.



System error 58 has occurred. The specified server cannot perform the
requested operation.



I can ping the rackstation, access it via the web portal and it even shows up in explorer under 'media devices' (but not under 'computers')


basic steps already taken:



  • tried another wireless network here

  • tried with firewalls disabled

  • No AV installed (only windows defender)

  • Reset TCP stack

  • IP only, rather than DNS UNC


Checked the following services are running:



  • Computer Browser

  • DHCP Client

  • DNS Client

  • Function Discovery Resource Publication

  • Server

  • SSDP Discovery

  • TCP/IP Netbios helper
    UPnP Device Host

  • Workstation


There are a number of servers / computers on my home network. I'd expect to be able to see them all in Explorer under 'Network' but only two show up. the surface book's own computer and my CCTV PC. I'd expect a lot more, which do show up on every single other machine without issue.


Pointers appreciated.


Answer



I'm not entirely sure what the issue was or the resolution. Steps I took:



  • Updated Rackstation to latest image

  • Changed the supported SMB version on the RS several times

  • Ensured that SMB 1 / 2 / 3 were enabled in Win 10 via PS


when I try and use UNC alone, Win 10 doesn't want to pass over my custom credentials but if I map the drive in CMD I can enter them.
This is the first windows 10 I've used with a Microsoft login rather than a local user, it will be the last.
