SoftPerfect Network Scanner is a free multi-threaded IP, NetBIOS and SNMP scanner with a modern interface and many advanced features. It is intended for both system administrators and general users interested in computer security. The program pings computers, scans for listening TCP/UDP ports and displays which types of resources are shared on the network (including system and hidden).

Changelog:
* Fixed DHCP module that mistakenly requested name server (option 5) instead of DNS server (option 6).
* Minor user interface fixes for systems with large fonts enabled.
* When scanning for shared folders administrative shares are no longer shown (reverted to version 4.x behaviour).
* Fixed 'argument out of range' message when scanning for shared folders.
