NetBScanner is a network scanner tool that scans all computers in the IP addresses range you choose, using NetBIOS protocol. For every computer located by this NetBIOS scanner, the following information is displayed: IP Address, Computer Name, Workgroup or Domain, MAC Address, and the company that manufactured the network adapter (determined according to the MAC address). NetBScanner also shows whether a computer is a Master Browser.

You can easily select one or more computers found by NetBScanner, and then export the list into csv/tab-delimited/xml/html file.

Fixed bug: NetBScanner failed to load the external MAC addresses file (oui.txt) when every line has 2 leading space characters. (Sometimes this file is provided with leading space characters, I don't really know why...)
Updated the internal MAC addresses database.

WakeMeOnLan allows you to easily turn on one or more computers remotely by sending Wake-on-LAN (WOL) packet over the network. This will return machines from a standby or turned-off state, useful for administrators or to save electricity until resources are needed. WakeMeOnLan also allows you to scan your network and collect the MAC addresses of all online computers. This information can be exported to a file.

Additionally, an available command-line interface can turn on a computer using a computer name, IP address, or the MAC address of the remote network card.

License: Freeware

What's new: >>

Added /cfg command-line option, which instructs WakeMeOnLan to use a config file in another location instead of the default config file, for example:
WakeMeOnLan.exe /cfg "%AppData%\WakeMeOnLan.cfg"
