I have a quite old CNC machine and need to gain access to a shared folder on Windows Server 2012 R2. It is perfect works with a shared folder on a non-domain server where a guest account is turned on.
But currently, I need to move this share on a domain fileserver and here I have an issue.
I tried to create a local account and use it on the CNC, without any success. I tried to allow guest, everyone and ANONYMOUS LOGON access to the folder, still no success.
I found topic with the guide on how to change all local security policies, did that and still no success.
Don't know what to do next. Is there a chance that someone in 2020 knows how to get access from Ms-Dos to a server share?

Update 2 I noticed that when I'm conecting from a windows 10 computer with an incorrect username, on the server event logs stored in Application and service logs - Microsoft - Windows - SMBServer security (Error SMB Session Authentication Failure)
But when I trying to connect from MS-Dos station logs stored in Windows logs - Security (Audit Failure)
