I'm operating on a wireless network on my laptop. I'm hooked up to a router that I share with my desktop computer and my dad's desktop computer. So all 3 computers can go online at once. But I've noticed that everytime I turn on my laptop I get the error "A Duplicate Name Exists on the Network." I have no clue what this means. If anyone out there can tell me what it means and how I can fix it, I would GREATLY appreciate it.
