LANscanner v2.0

Way back in early 2009, I wrote a post entitled: How to Determine the Master Browser in a Windows Workgroup

Since then, quite a number of people have downloaded and used my little LANscanner program for displaying the IP addies, MAC addies, workgroup, and Master Browser of all the gizmos on their local network.

One problem: With the release of Windows 10 1709, it stopped working.

Well, I’m happy to announce the release of LANscanner v2.0!

Yeah, that took awhile. I’ve been busy!

What’s New

Version 2.0 of LANscanner works a bit differently.

Since the net view command no longer works in Windows 10, I had to change how the whole shebang works. Now, it goes something like this:

  • arp -a command gets a list of all IP addies and MAC addresses of gizmos on the LAN
  • nbtstat -n / ipconfig are used to get your puter’s IP addy and MAC address
  • nbtstat -A [IP_ADDY] is called on each result to get the workgroup name and Master Browser status

Note that because LANscanner 2.0 works differently than v1.68, you may want to stick with v1.68 if you’re still using an older version of Windows.

The options are the same as before:

  • -ip  =  Sort output by IP addy instead of puter name
  • -w WORKGROUP  =  Scan only the workgroup called WORKGROUP
  • -e WORKGROUP  =  Scan all workgroups except WORKGROUP
  • -n = Suppress the “Press any key to exit…” message at the end
  • -m = Only displays the MASTER browsers found
  • -nodeip [IPv4 addy] = Specify the IP of the network adapter you want to scan from in the case of multiple network adapters (including VirtualBox Host Only Network adapter)
  • -g = Include the Default Gateway
  • -s = silence the printing of selected command-line options

Also, note that the arp command will also see things like networked printers, NAS devices, and even your home router – although the router will probably not show up since it’s usually the default gateway, and the default gateway is ignored by LANscanner v2.0 (use -g option to include it).

Finally, not all networked gizmos like printers and NASes have a workgroup set, so those fields might be blank in the results. Some printers will also show their name as “–” if they are in sleep mode.

As usual, LANscanner v2.0 speaks English, Spanish, French, German, Swedish, Polish, Norwegian, Portuguese, Japanese, Dutch, and Czech.

Give it a whirl!

UPDATE 31 Jan 2019: v2.01 is out. Added -g option to include the Default Gateway, and the -s option to silence the printing of selected options
