the external drive is connected through an old desktop running XP. I have went through that and made sure everything was allowed, and set up correctly. I checked the IP address, it has not changed. My laptop finds the network name but keeps telling me it cant find the external and that i may have spelled the drive name incorrectly (which i have not.) I also disconnected basically everything, the mapped drive, the external its self, shut down both computers, still nothing. And now since I disconnected the mapped drive, it is unable to find anything now. My biggest question is, how did i work saturday, nothing has been changed, and now it doesnt work???
