NIS, root access

[Dan Track]

Hi

Got a slight problem on my workstation. Basically when fedora boots up
sometimes NIS doesn't get started, so when the login prompt appears I
try to login as any user even root but the system won't let me in. The
only way in is to reboot and hope NIS works or reboot to single user
mode and turn of NIS. Does anyone know why I can't login in as root
when NIS is down even though the root password in stored on my
workstation and not in NIS.

Thanks
Dan
