I currently have a Synology NAS at my office that I wish to connect to remotely with SMB. This works perfectly fine on my MacBook, I use finder to connect with smb:\\<domainname>\<share>, but I cannot do the same on the Windows 10 machine. The network environment is exactly the same. I tried mapping a networking drive with \\<IP>\<share> and \\<domainname>\<share> but it fails to connect every time. Any suggestions on how to get it to work?

Thanks in advance,

  • Fails to connect? Do you get any messages/errors? Also, make sure you're using backslashes in the entire UNC path. You've still got forward slashes in your question and I'm unsure if that's a typo or if that's actually how you're trying to connect. – joeqwerty Jul 18 '17 at 0:56
  • It says "The folder does not appear to be valid. Please choose another." I have corrected my typos above. – Gundamire Jul 18 '17 at 3:44
  • Can you navigate to just the hostname? (i.e. do not go to the shared folder, just the IP address/hostname.) – Davidw Jul 18 '17 at 5:41

Not enough details provided, so many reasons can be behind this problem which looks to be related to the Windows machine. Try to verify these steps :

  1. Check if NetBIOS is active on the machine : Activate NetBIOS
  2. Check smb version : SMB version Check
  3. Check your firewall and settings related.
  4. Check the rights in the NAS server : the user you are connecting with in Windows has the rights to access that folder.

Note that smb/CIFS has many issues with Windows.

  • NetBIOS is not required to access a share. It is also a security problem and should not be enabled. – Greg Askew Jul 30 '18 at 11:41

You must use backslashes and not forwardslashes:

  • Oh sorry, that was a typo in my original original question, I’ll fix it now! – Gundamire Jul 18 '17 at 0:50
