I am working on 2 Windows 11 laptops, 1 Pro and 1 Home. These both have a folder connected to an old AXYZ CNC router that is controlled with Windows CE. Back in April, the laptop running Pro stopped connecting to the router. It says the path does not exist. The one running Home connects just fine and and old Windows 10 Home laptop connects fine. This tells me the issue is one of the security items with Pro.
I have SMB1 enabled in additional features and turned off password enforcement with Powershell. I am pretty sure I created a registry item for SMB1 but it's been long enough that I am not sure if I did or have just read the same article 2 or 3 times. Assuming I did create a registry before I tested them last (two weeks ago), it still wouldn't connect. I am running out of places to look and trying not to wipe the computer. Thank you in advance for any help.

I followed that for both the server and the client side and I am still getting the same error. SMB1 is showing that it has all the needed permissions. I even made sure that SMB2 is up and running to make sure there is no issue with either connecting. I did reboot after making the registry changes but not after running the cmd commands to enable client side SMB1.
It is definitely an issue with Windows 11 Pro not connecting to the CNC router. The two Home edition computers still connect just fine. I think I am getting closer to a full wipe and reload of 11 Home on this laptop.
I pulled the logs and it looks like it is a client side authentication issue. I changed the registry to allow unauthenticated sessions but it looks like I missed the part on the local group policy.

Hi,
Please open the Registry Editor and navigate to the following path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
On the right side, look for the DWORD SMB1. If it's present, the value should be set to 1 for enabled. If it's not present or set to 0, SMB1 is disabled.
Best Regards,
