I installed Unassigned Devices on the new Unraid6 box. When I try to add a share, it can't find the old server. I tried by name and IP address.
I'm not sure it's related, but one of the reasons I'm retiring the old box is I cannot access it from Windows 10 PCs. I can access it with a Win7 VM running on a Win10 laptop, but only by ip address, not name. So maybe something's goofy with the sharing set up of the old 4.7 box?
