Hi there!... As i know, is that about Windows Services... I just disable some services in a XP SP2, and i had the same problem. So, i've restored the system and works again. Now, i'm gonna disable again the services but i will take note about them. I'll see if a services is doing the problem. EDIT: Well, the error in XP SP2 was in EventLog Service, when i disable it, the Networks didn't show. And when i enable it, all works fine. But, in SP3 doesn't work. I give up. Anyone can help us, please?... Thanks!... (Sry for my english)
