SoftPerfect Network Scanner is a powerful, portable tool that can help manage, troubleshoot and check the security of any network.
Just give the program an IP address range, click the Start Scanning button, and it'll use ICMP, NetBIOS and SNMP to check everything that's currently connected to the network: PCs, laptops, router, network printer, anything that has its own IP address.
At a minimum you'll get a list of each connected device, including its network name, MAC and IP address. And you can then manage PCs or laptops from here, perhaps sending a message to the currently logged-on user, shutting down the system remotely, or sending a Wake-On-LAN message to start a system that's currently turned off.
Even better, SoftPerfect Network Scanner will also detect and display resources that are shared on the network (both administrative and hidden), so you can easily check that all your networked systems are properly configured. And if you spot something that looks out of place then double-clicking it will open the share in Explorer, a quick way to find out exactly what's being exposed.
The program is multi-threaded for maximum performance, highly configurable, and provides many other ways to remotely administer networked PCs. You may be able to find out more about their services, access Registry information, even send WMI queries, although you'll need some WQL (WMI Query Language) knowledge to get the most from this.

Added reading MAC addresses from the ARP cache if sending an ARP request fails.
Made several dialog boxes suppressible with an option not to show them again.
Allowed to create batch files without %0 and %1 placeholders.
Fixed looking up friendly names and NIC vendors when using different MAC address formatting.
Added duplicate MAC address detection and a unique/non unique filter.
Added device deletion in the main view and drag-and-drop in the bookmark manager.
Fixed filtering out entries containing the string <empty> when an Empty/NotEmpty filter is used.
