How does netViz discover my network?
netViz uses Microsoft LanManager APIs to perform its discovery. This is the same mechanism used by the “network neighborhood” icon on your desktop. After it has found the servers and you have selected which ones to gather information from, it will again use the LanManager APIs to discover which shares (or volumes) a particular server has. If the discovery process appears to be slow, go into your network neighborhood to see how fast it is getting the servers and showing the shares on them. This will give you an idea of how long the entire process will take.
