Hi, I followed this article: https://learn.microsoft.com/it…nd-smb3?tabs=group-policy

but I still can't connect to the NAS, are there any settings I need to check in the UI?

Ciao, l'articolo che hai postato spiega come accedere a una cartella condivisa, via SMB, su Windows.
Nel tuo caso, vuoi accedere da Windows a una cartella sul NAS; la richiesta di credenziali non dipende da Windows, ma dal NAS.

Crea sul NAS un utente (con password), associalo alla cartella condivisa e, quando Windows ti chiede le credenziali, inserisci quelle.

In Windows 11 try this, it worked for me, although the smb1 protocol is obsolete, it is an alternative to access shared folders

You still have to enter the name "guest" in that Windows dialogue. On OMV make sure your shared folder has the permissions of "others" set to read/write/execute.

If you are in doubt about the changes to be made to Win11, here's a recent post re: Windows 11 24H2 and Insecure Guest Logins settings:

Umleitung

AFAIK the group policy edit (gpedit) should be sufficient.

Hi, I've got the same issue today (with a brand new PC with w11 24H2)
typing this in powershell solved the issue :

Set-SmbClientConfiguration -EnableInsecureGuestLogons $true -Force

Set-SmbClientConfiguration -RequireSecuritySignature $false -Force

Set-SmbServerConfiguration -RequireSecuritySignature $false -Force

(hope it can help you)
