I need to create a network map that shows servers, printers, switches with their names and IP addresses. So far I haven't found anything that does that. I've tried What's Up Gold and spiceworks.
The Dude! That thing is neat, I can't remember where I found that originally but it's been awhile since I last updated the poor thing. However along with The Dude, I use Flukes EtherScope it isn't software but a portable unit I can plug in where I feel there might be an issue is a good thing to have on hand.
Software wise I don't use much else then The Dude.
