I have a Win 7 Pro 64 desktop and a Win 7 Home Premium laptop networked ( via workgroup not homegroup) I went to add a Vista laptop to workgroup and it asks for user name and password. Everything is set for no password, all folders, drives etc are set for sharing. At one point I was able to view the desktop drives etc but could not access them as I did not have permission. I went into security tab of drive and edited it to include "everyone" with full access and that seemed to work until I rebooted and now I am back to square one with only being able to see the destop computer under networks but I can't see or access any drives as it keeps asking for user name and password. I never had issues like this before. I am stumped??
