Heres problem number One. WinXP Home = WinXP Pro - (service control +

are you using mkpasswd and mkuser?


Also, Administrator is availible under home for more that recovery
mode -- look at TweakUI's user hiding, theres an option to allow
Administrator to log in

It may be that you are setting access permissions for /bin/bash wrong
-- they should be rwxr-xr-x (744?) and belong to nobody.

are you creating limited accounts or "administrator" accounts?

Have you tried using the Non-Graphical (username: password: Domain:) login?
