I saw a similiar thread on here but it didn't help me. I networked a Vista and a XP computer together. And the Vista can access the XP with no problems. But when I try to access XP to Vista, it ask for a username and password. Both computer do not use any password whatsoever. The XP has two users on it but there is no login password. I open the the window to: User Account-Advanced-Manage Password and it was empty. And so what do I need to do, to get rid of this password box. Or what do I put in the blanks? I never enter any password for networking. I'm puzzle can someone help me?
