i have a "simple" home network running. internet connection -> linksys router which provides wifi and connects to a switch for 10+ wired connections i have Mac OSX, XP, and Vista machines running on these. I also have a "time machine" backup box as well as a WD network drive. Day comes along when i need another network drive, i go back and buy another WD one. I plug it in, and now computers can't see eachother in the network center (on either windows or mac) yet if i type, for ex \\mybookworld\ i can access it. The strange thing is that upon removing this new drive, the problem did not correct itself. Any ideas?
