Hi Dave
Is the Linx on the same network IP range?
If it is then make sure the Linx has got the option for SMB2 enabled. On the Linx, open the Control Panel (not settings!) and select 'Programs and Features'. From there, select 'Turn Windows features on or off' and look for the SMB clients (turn them all on for now) and reboot. Can you see the Buff now?
Cheers
