SuperScan 4 is an update of the highly popular Windows port scanning tool, SuperScan.
Windows XP Service Pack 2 has removed raw sockets support which now limits SuperScan and many other network scanning tools. Some functionality can be restored by running the following at the Windows command prompt before starting SuperScan:
net stop SharedAccess
Note that SuperScan 4 is intended for Windows 2000 and XP only. Administrator privileges are required to run the program. It will not run on Windows 95/98/ME. You may need to try SuperScan v3 if this will not work with your system.
