Running 64 bit Windows 7 I get an error message Of "Fail To Map Drive" when using the D-Link Easy Search Utility. My other 64 bit Windows 7 computer has no problem mapping the two drives. It seems to be one computer that has the problem. When the problem computer boots up I sometime get an error massage saying it can not find the drivers for the DNS-321. I have run the configuration wizard several time but still have the problem. I believe I must have a setting wrong in that one computer. All the rest, including a Windows XP computer, work just fine. Help.
