I have had to replace a Windows XP computer that crashed on me with a new Windows 7 Pro 64 Bit computer. Everything worked fine and the new computer can access all my computers on my LAN...the problem is, when I try to access the new Win 7 pc from my other Windows XP computers. When I try to access it through Windows Explorer I get the log on pop-up asking for username and password, which I do not want. I want it to access it directly without any kind of log on. I have a Homegroup setup with my other Windows 7 computers...just have a problem going from XP to 7...Suggestions?
