I installed one Windows Server 2025 on hardware, then I installed other Windows Server 2025 on Proxmox VE.

I tried to map the samba sharing network driver but, I have got the same result on both servers: -

"The mapped network drive could not be created because the following error has occurred:

An extended error has occurred."

As usually I enabled "Insecure guest logons".

It works on any Windows Server 2022 and works on any Windows 11, but do not work on Windows Server 2025.

Is there any solution?

Notice! The folders shared on any Windows PC the Windows Server 2025 maps as usually.

    The issue is the new security signature requirement in 2025. I knew they enabled it by default in 2025, but I thought I had already disabled it. Apparently, I hadn't.

    Set-SmbClientConfiguration -RequireSecuritySignature $false

    You can also disable it via GPO by setting the "Microsoft network client: Digitally sign communications (always)" option to disabled in the security settings.

    Thank you for your reply.

    Excuse me, but it is not the case!
    I work as a system administrator in several organizations for more than ten years for now.
    I checked it out many times.

    I changed samba shared directories.

    I tried it on Ubuntu server 22.04 and on Ubuntu server 24.04,

    I tried it on a directory where the login and the password do not need.

    I tried access on the shared directory where the login and the password needed.

    It is something else.

    With best regard,

    Hello

    You can try enabling the option to connect to other credentials when associating the shared drive.

    Thank you very much!

    But I tried this before I wrote my request. It does not work.

    More than that, there are, at least, two options:

    -          The access to the shared folder does not require a login and a password (why and what in this case I have to enter?);

    -          The access to the shared folder does require login and password.

    I have got the same error notifications.

    Hi Hryhorii Bakalo,

    Thank you for your reply.

    This problem may be caused by invalid user credentials. I suggest you open the "Control Panel", find the "Credential Manager", delete the related "Windows Credentials" and try to remap the shared folder.

    Best Regards
