Hi,

since some updates of Wiundows 11 I'm experiencing problems with connection to shared folders.

The share folders are protected by user/password pairs on Windows 10 and QNAP NAS (linux) .

Issue looks very simple:
I try to connect to computer I got password form, I fill in the credentials and each time I receive message that the credentials are wrong - what is going on???

The credentials work very good from other machines and event from the same machine but different system (linux).

Moreover, only machine with Windows 11 has that issues.

Moreover, after login to machine with Win 11 my NAS reporting lot of failed logon with logins: [WIn11_name][user] and other login form IP of my Win11 machine

Why Win11 is trying to login to server using all of my credentials, all of user (even if they aren't logged in to the machine). It seemed to me as a credentials leak...

What is wrong with Windows 11???

What can I do?

EDIT: One of the issue dissapears if I connect from Win11 do Win10 share using account with login without international characters...
So one of the issue can be related to missing proper support of international characters in usernames/login via SMB in Win11.
Does anybody experienced something like that?

    check the SMB version that's used by your NAS device and make sure you enable it on Windows 11.

    Hello,

     

    Thank you for posting in Q&A forum.

    To further troubleshoot this issue, please kindly follow below steps:

    1.Collect SMB configuration fron client and server by PowerShell command. Check if there's any difference:

    On Client:

    Get-smbclientconfiguration

    On Server:

    Get-smbserverconfiguration

    2.Reproduce the issue and capture the progress by wireshark or network monitor.

    3.Get an error screenshot when it reproduces.

    4.Forget the network driver and connect to it again.

    5.Start the computer in safe mode and see if this issue will reproduce.

     

    Best regards，

    Jill Zhou
