safely ignore that message. Simply click the scan button, and it
goes to work. It looks across your network, finds all PCs on it,
then gives you quite a bit of detail about each. In addition to the
local IP address of each PC, you?ll also find what ports are open
and what ports are closed on each PC. Armed with that information,

information, such as what services are running on each PC, the
NetBIOS names (if any) associated with each PC, and even a list of
users and groups on each PC. If any PCs have shared folders, you?ll
