Hello,
I've run into an issue with a laptop that I haven't been able to resolve. Win XP/ME 2000 SP-3, Dell with internal wireless. Used to connect to all devices in a home network. Suddenly stopped. Network connection is good. All network devices display as {Computer} "unknown" and {Network Location} "Internet" in "My Network Places". Three wired network computers and two other wireless work fine including my "test" MacPro. In addition to the wired computers there are 3 printers on the network accessed through their USB connected PCs.
