Network file sharing not working between Windows 11 & Windows 10

The hosts file is read only protected. Below Bat script is what I use to change the r attribute and edit the file. Ok I use Notepad++ and have Set a variable for OneDrive... Here's the script... Have fun.
@echo off

Hi,

I used a NET USE DOS command: NET USE z: \10.20.30.40\Documents for consistent access.

I can also browse \10.20.30.40\Documents in the file browser.

I believe the failure is in the way Windows 11 uses DNS, from what I'm seeing. Once you browse to the Win 11 machine from Win 10, the IP address then displays in the network browsing tree, at least temporarily, but you still cannot use the PC's named entry in the tree to access the share.

Because my Win 10 PC is a work PC, I cannot edit the HOSTS file. I wonder if that wouldn't work for this issue.

I can ping the Windows 11 machine from all of the Windows 10 systems, but that's about as much connectivity I get.

Island fishing, when you say Ping, are you using the Name, or the IP?

I have found that using the IP seem to work for me. e.g. \111.222.333.444<sharename>

I then map a drive using the NET USE DOS command.

Yes. It was the simplest option even though it doesn't have secure boot, TPM or a supported processor. It works perfectly.
