When trying to transfer files to network drives, we are experiencing the same error at random times. 0x8007003B error.

enter image description here

This started only about three days ago and is been affecting several users. How/ where to start troubleshooting this kind of issue?


  • What kind of network drive? – Moab Oct 25 at 18:27

  • Is it a nas or another PC? – Moab Oct 25 at 20:43
  • This is a Buffalo TeraStation model: WS5400R1604 running Windows 2012 – Tiago Oct 25 at 21:19
  • If you have AV software, turn it off and see if it still does it. Also try turning of any firewall, do these one at a time to see if it either one causing the issue, there is a software updater for that model on this page>>>>>>>>buffalotech.com/support/downloads/… – Moab Oct 25 at 21:37
