I cannot access my Synology NAS from one the clients on the network, using Windows Explorer.
When I click its icon in the Network section, I get an error:
"Couldn't access \SynologyNAS" "Error 0x80070035. Network path not found"
Problem diagnosis actually doesn't find any problems.
Also, all other applications can locate the SMB shares:

  • This NAS is accessible through Win Explorer from every other client on the local network.
  • From this machine, the Synology Drive Client, as well as Synology Assistant can access and use it.
  • Going to the NAS's IP in the browser from this machine, it's accessible.

I'm posting this here because clearly, there is a problem with Explorer.

Only Windows Explorer is not getting through. Here is the output of some diagnostic commands suggested in Synology forums:
