Hi, I have a samba setup as a PDC. Everything works fine - but today I logged onto a workstation locally (not to domain) with the user Administrator - and I saw that I have access to all my shares and that this user is mapped to root I don't use a "username map" file ..... I disabled the administrator account in smbpasswd - but its still the same. I also have a password set to the admin account in smbpasswd but logon to the workstation where the password is empty!!!! What can I do ? How can I disable the administrator - account. Thanks a lot Oliver
