I assume they are all on the same Workgroup?

You could try using a FTP client instead - such as WS_FTP_LE which is free.

Or, do a search - your issue has occurred many times before.

Yes, make sure workgroup in Windows 3.11 is set to homelab even if not a member of the domain. This will allow windows to match the homelab\user format the server is expecting.

Create a share on the Windows 3.11 PC and check if the modern PC can access that? I've had it a few times when sharing works one way but not the other.

Hi, it reminds me a bit of this old thread here: Windows 98 PC suddenly stopped appearing in the Network on my main (Windows 7) PC
Long story short, Windows 9x and WfW used permissions per folder; Windows NT uses permissions per user.
That's why the password thing happens, I think. Also, old Windows used NETBIOS and Lan Manager protocol (aka CIFS, SMB1).

Good luck! 😀 🤞

PS: On modern Windows (NT6+), there's a "homegroup" network type in addition of the old "workgroup" type.
Classic Windows needs the workgroup type. Making sure that workgroup name and domain name are same does help, maybe.

On my systems at least, if you install NetBEUI on anything XP and older then there's no trouble mapping drives between them and having 2-way access.

But WFW 3.11 won't access any of my NAS's directly, so I used WS_FTP.

Speaking of vintage technologies like FTP, there's also serial connection via null-modem cable.
Norton Commander 5.x and FileMaven v3 (DOS) do support it, I think.

Windows 9x and onwards do have Direct Cable Connection utility that's more comfortable than FTP.
It seems to be derived from LapLink technology, which is included in MS-DOS 6.x.

Hi,

thanks for the Input.
Machine is in the same Workgroup (PCQ.LOCAL)

But the FTP Thing I will try out, not as confortable as a direct mapped drive (was hoping to run CD Games from the Share instead of burning these CDs from .ISO)

On Weekend, I will add another, non Domain Server on my ESX (maybe an older Server 2003 or so) and try a bit more. Dont want to „unsecure“ my running file server much more with legacy auth methods 😀 Should also do an isolated VLAN maybe.
