After reading another thread on here just know I thought I would ahve a go at mapping a network drive to my pc to ease the trasnfer of files from downstairs to upstairs. When I try to add a drive I choose the drive letter it I start to browse to th drive I wish to map and i see the computer name listed and i click that and then it asks me for a username an dpasssword but that pc does not use a username nad password so what do i type in there?
