IP Scan does not show NetBios names

Tools/IP Scan does not show NetBios names. It would be very useful.

Strange - even last MT /6.39.2/ IP Scan does not show NetBios names
Any ideas ?

Firewall?

IP scan on my routers (v6.9.32) shows netbios names just fine.

all disabled

Not firewall on the router but on Windows.

all firewalls are off and all hosts are visible in windows
