what protocol does Windows 10 use to discover network hosts?
by mfoley from LinuxQuestions.org on (#4TCGG)
Not sure this is a Linux question, but I'll start here. Our newly installed Windows 10 computers have some issues listing hosts on the network. Only two of 4 Windows 7 computers show and only one of 6 Windows 10 computers show. No Linux or Mac computers are listed. When viewing network computers from the Windows 7 hosts, all computers, Windows 7, Windows 10, Linux and Mac, show up. This issue for Windows 10 is all over the Internet. In researching this issue, a suggested solution was to set Control Panel > Programs & Features > Turn Windows features on or off > SMB 1.0/CIFS Sharing Support, and checking SMB 1.0/CIFS Client and SMB 1.0/CIFS Server. After doing that, all Network hosts (Win7, Win10, Linux, Mac) show on the Windows 10 computer.
Supposedly, SMB 1.0 is obsolescent and insecure, but Windows 10 cannot see all network hosts without this setting, and why it can see the odd Win7 or Win10 computer or two is inexplicable.
The question here is, what would the Windows 10 machine be sending to the Linux host for the Linux host to reply back acknowledging its presence? Why would Linux be responsive to SMB 1.0 and not a more recent version of SMB? Can I determine what version of SMB is enabled on Linux? Can Linux be set to use SMB 2.0 or whatever?
Note that SMB in this case refers to Server Message Block, not Samba.
