I have a MacBook runing OS 10.5.5 and a Windows XP Pro Desktop. I have set up file sharing on both machines. The account username and password on the Mac is not the same as the account on Windows XP because the Windows machine is my dad's. I can connect to shared files on Windows from Mac by typing my dad's username and password when prompted. Only that UN/PW has access to the file shares for security reasons. But I cannot connect to my Mac from Windows XP because I am not prompted for a UN/PW. I get no error message, all I see is "Printers and Faxes" because my shared "Home" folder is set for; I have "Read & Write" permissions but "Everyone" has "No Access". Why do I not get a password prompt when connecting to the Mac? How do I get one? Thanks. Note: The mac is sharing files because if I give "Everyone" "Read & Write" permissions on my "Home" folder I can connect. but I still get no password prompt. Also attempts to connect to shared files on my brother's ibook G4 running OS Tiger from Windows will prompt for a password. If my brother enters his UN/PW all is well. So I think this is a Leopard Issue.
