That might be a 'Local Master Browser' issue (?)
I use a laptop from my work, which has one domain
but all other machines, including the unraid, belong to a specific workgroup
When I connect to the settings page of unRaid, under SMB I see that currently elected domain is the one of my work, not the local.
And something weird, I do see that this elected master browser change for 1-2 second to this of my home, but then immediately changes back to domain of my workplace
weird
