I have a Mac Mini running OSX 10.7.5, I can log into it through a laptop running Windows 7 and browse it's files.
I have another machine running Windows 8, it can see the Mac Mini, but when trying to connect, a "Windows Security" pop-up appears asking me to log in. It automatically adds the DOMAIN to the username field like:
Username: <DOMAIN>/mini Password: .........
Authentication fails. Any suggestions?
