Network Scanner

Network Scanner is a free application geared toward network system administration and specializing in scanning those networks. It has the ability to scan a complete range of previously specified IPs, checking the MAC-address and ping response time, even through routers if necessary.

In a similar fashion, it scans all of the network's shared directories, including those that are hidden. It can even create virtual units shared from those directories.

It's programmed to be a portable tool so that you can access any network at any moment. To make it as mobile as possible, it doesn't require administrative permissions or installation.

All of this makes Network Scanner a useful tool that you should keep in mind.
