UNRAID SMB and Windows 10 Prompting for Login Issue

Recently rebuilt my Windows 10 (1909) desktop and I’ve been unable to get to my UNRAID shares. It’s been driving me crazy as nothing with my servers or network has changed. I can still manage UNRAID with the root and password I’ve always used so it has to be something with my freshly imaged computer.

Turns out Microsoft has made some adjustments to network shares. (I’m using Win10 Pro/Enterprise. There is one little group policy object we need to change.

Open a command prompt on your windows machine and type in: gpedit.msc then enter.

What Policy Needs To be Changed

Computer Configuration > Administrative Templates > Network > Lanman Workstation > Enable insecure guest logins.

Edit the policy and enable it.

Your shares should be accessible again! No need to reboot or log off.

If that doesn’t work try enabling SMB Windows Feature.

Start > “Turn Windows features on or off” > SMB1.0/CFS File Sharing Support

If none of this works the last thing to try if you’re prompt for a username and password is

  • Username: guest
  • Password: 1234

  1. Yep, Microsoft made a change to SMB in 2018 or 2019 for security reasons.

    Do *NOT*, under any circumstances, enable SMB v1 OR enable SMB access using insecure logins. This opens you up to a host of security holes if you access other shares via SMB from any other source. It is a Bad Idea.

    Either set up a dedicated user on unRAID for SMB access and use that, or use the ‘guest’ and ‘1234’ method detailed at the bottom of this article.

  2. omg it worked. Thanks alot.

    I just had to restart computer or remove the password remembered by windows. To remove password from windows I searched for “credential manager” in windows and remove for that Unraid server.
