Windows 10 Cannot Connect to NAS SMB Share

Reader Question:
“Hi Wally, I have been using my network hard drive to share files for a while without issues. But, it is not working now since upgrading to Windows 10. I have not changed anything about my setup whatsoever. I can still see the shared files on other devices as well.” – Justin H., United Kingdom

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win7, XP, Vista – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: Many people have complained about not being able to use their NAS devices the way they did before upgrading to Windows 10. Usually, these people are using Windows 7 or an older operating system e.g. Windows XP prior to the upgrade. Please keep reading ahead for potential solutions.


The user is not able to share files over the network to a NAS using SMB.


Here are some ways to fix the NAS SMB sharing issue on Windows 10.

Enable SMB 1.0 in Windows 10 

Press the Windows Key and type control panel. Click Control Panel from the search results.

Windows 10 -- Control Panel - Windows Wally

Click Programs from the Control Panel.

Windows 10 - Control Panel - Programs -- Windows Wally

Click Turn Windows features on or off from the screen as shown below

Windows 10 -- Control Panel - Programs - Turn Windows features on or off - Windows Wally

Scroll down and enable SMB 1.0/CIFS File Sharing Support by making sure that its box is checked.

Windows 10 -- Control Panel - Programs - Turn Windows features on or off - 2 - Windows Wally

Update NAS Drivers or Software

If your NAS device comes with a software for configuration and viewing the files, then please try updating that software. Maybe the manufacturer has already released an updated version of its drivers for Windows 10 and you’re still using the version made for the previous version of Windows.

Is Your PC Healthy?

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.

Happy Computing! :)
