I've tried agaist XP, Win7 and Server 2012 R2. VMs and real machines and 2 dirrerent networks.

Typical output:

 nmap --script smb-enum-users.nse -p445 192.168.1.70

Starting Nmap 6.47 ( http://nmap.org ) at 2015-06-08 10:32 EDT
Nmap scan report for 192.168.1.70
Host is up (0.0012s latency).
PORT    STATE SERVICE
445/tcp open  microsoft-ds
MAC Address: 00:1C:42:6F:D1:A1 (Parallels)

Nmap done: 1 IP address (1 host up) scanned in 15.79 seconds

Ideas? Suggestions?

Thanks guys!

The -vv and additional ports have same results.

the -vv doesn't show (to me) and error/issues

if you want to test and you are on a windows box, try an nbtstat against a known host that has netbios names enabled on the nic settings (and netbios over tcp if not using UDP port scanns) and the services "computer browser", "server", and workstation are all up(on the target).

Alternative is try nbtscan (which can do more than one IP at a time like nmap does, ie: 192.168.1.0/24), but just because a port is open, doesn't mean the services for it will respond with the netbios name.
