How to Fix: NAS share access on Windows 10 getting error "A specified logon session does not exist. It may already have been terminated "

The error 'A specified logon session does not exist. It may already have been terminated' occurs when attempting to access a shared folder on a Windows 10 machine using Azure authentication through PINs. This issue affects users who are trying to access shares secured with passwords on NAS devices, such as the WD Ex2 Ultra.

This error is frustrating because it prevents users from accessing their files and folders without having to use their password instead of their PIN. In this troubleshooting guide, we will explore the root causes of this issue and provide two primary fix methods to resolve the problem.

⚠️ Common Causes

• The first main reason why this error happens is due to the way Azure authentication works with Windows 10. When a user attempts to access a shared folder using their PIN, the system creates a new logon session that is not compatible with the existing password-protected share on the NAS device. This incompatibility causes the error message.
• An alternative reason for this issue could be related to the specific settings or configurations on the Windows 10 machine or the NAS device itself.

🔧 Proven Troubleshooting Steps

💡 Conclusion

To resolve the error 'A specified logon session does not exist. It may already have been terminated', you can try enabling Kerberos authentication on your Windows 10 machine or configuring the NAS device settings to use this method. By doing so, you should be able to access shares secured with passwords using your PIN. If you encounter any further issues, please refer to our additional resources for further assistance.
