I am thinking of a network browser project. Similar to the 'Entire Network' in windows Explorer where PC's are listed in the associated workgroup/domain etc. I am fine on the treeview its finding out what is on the network that I don't know about. Selecting a particular machine in the treeview will display details about that particular machine. Obviously the latter depends on security and access rights to the individual machines.

Can anyone help with the network sniffer part of the project.
