Comment 74 for bug 1778322

The "windows network" tab depends on an election to happen between the smb servers, and a master browser being elected. It's the master browser that is contacted for the list of machines in the network. If that machine has smb1 disabled, for example, then this won't work, because it will hit #1828107 (that's my understanding).

I suggest to focus on the test case presented in the bug description. If there are still cases where it doesn't work, then it's a separate bug, because disco has the same fix in place as we are applying here.
