Disable Password Sharing

[CorreoMail]

Ive installed Server Core RC2, I want to share X folders of that server so I turned off the firewall and now I can acces trought the Server Name but it still asking for password so I want to turn off the Password Sharing but I cant find the way.

Is ther anyidea to solve this?

If you set everyone as shared permission, it shouldn't ask for passwords
