Windows 10 users experiencing a password error when connecting to a Samba share using the net use command or Map network drive dialog are affected by this issue. This frustration can be attributed to the fact that other clients, such as Android and Linux devices, can connect successfully with the same user credentials.

The root cause of this problem lies in the Windows 10 Pro version and its interaction with Samba shares. The error is typically due to an incorrect or outdated password policy configuration on the Windows side.

💡 Why You Are Getting This Error

  • The primary reason for this issue is that Windows 10 Pro (version 1511, build 10586.589) has a known limitation when it comes to Samba shares and password authentication. The version of Windows is not compatible with the latest Samba protocols, leading to authentication failures.
  • An alternative possible cause could be an outdated or incorrect configuration of security policies on the Windows side. This includes settings related to NetBIOS, SMBv1, and NTLM authentication.

🚀 How to Resolve This Issue

Adjusting Windows Security Policies

  1. Step 1: Open the Command Prompt as an administrator and navigate to the directory where you want to create the new registry key. Run the following command: `reg add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Samba /v EnableSmbAuthNTLM /t REG_DWORD /d 1 /f`.
  2. Step 2: Next, run the following command to enable NetBIOS over TCP/IP: `netsh int ip set interface 'Local Area Connection' type Ethernet, TCP/IP and enable netbios over tcpip`.
  3. Step 3: Restart your Windows machine after making these changes.

Upgrading or Downgrading Samba Version

  1. Step 1: Check if there is a newer version of Samba available for your system. If so, update to the latest version using `sudo apt-get update && sudo apt-get upgrade samba` (for Arch Linux users).
  2. Step 2: Alternatively, you can try downgrading to an earlier version of Samba that is compatible with Windows 10 Pro.

🎯 Final Words

To resolve this issue, it's recommended to adjust the Windows security policies or consider upgrading/downgrading the Samba version. Additionally, ensure that the user credentials are correct and the password policy configuration on both the Windows and Linux sides is up-to-date.
