SoftPerfect Network Scanner is a free multi-threaded IP and NetBIOS scanner. Both system administrators and users who are interested in computer security can use this. The scanner pings computers, scans for listening TCP ports and shows what types of resources are shared on a network (including system and hidden). It allows you to mount shared resources that are found by the program as network drives, simply browse them using Windows Explorer, etc.
