Hello,
Thank you for posting in Q&A forum.
If your windows client is managed by your organization, it could be caused by the GPO setting update issue. You can try below steps to allow Anonymous Access:
1.Open group policy editor and navigate to: Network Settings > Computer Configuration > Administrative Templates > Network > Lanman Workstation.
2.Enable Insecure Guest Logons: double-click on enable insecure guest logons, select Enabled, and click OK.
3.Restart the Windows Client to apply the changes.
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best regards,
Jill Zhou
