Why is Windows 10 Version 2004 preventing logon scripts from mapping NAS drives at first logon attempt?

Since we updated Windows 10 to Version 2004 that all the machines in our domain stopped mapping NAS drives at first logon.

When the users start the machines and logon the logon script maps correctly the drives in several servers but not in the NAS.

If they logoff and logon again then the mapping is done correctly.

The problem occurs sistematically and started only after Version 2004 was installed.

It has nothing to do with SMB 1.0 being enabled - it was already enabled before Version 2004 as it was needed because we are talking about an old NAS.

Direct SMB appeared enabled and we disabled it, but it didn't solve the problem.

    I've posted this issue on various forums, MS Technet included.  I either get NO answer or simply get ragged on for daring to use such an old protocol on a 17 year old OS.  Admittedly that's the answer to those having the issue for regular MS OS's like 2003, it won't fix the issue to those using older SAN hardware that can't be upgraded. 

    I fear we will never get this issue resolved, it will instead fall to us to replace hardware / OS software to make the issue go away.

    We have the same problem.

    I hope MS resolve it asap.

    Any chance you are using Guest access on your NAS and you need to change the following key and restart your PC/laptop?

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters]

    "AllowInsecureGuestAuth"=dword:1

    No chance.

    Each user has its own credentials.

    And as the article points out, that occurs in Windows 10 version 1709 and later, but in our case the problem started only with version 2004.

    But thanks for the suggestion.
