[Samba] Login denied after joinined Samba PDC

[Eric Halverson]

Currently running samba 2.2.7 on rh8

I have not had any problems until recently, and I'm not sure exactly
what would have caused this problem.  I have no problem joining a w2k
workstation to my domain, but whenever I attempt to log into the domain,
i receive the following error on the workstation:

The system cannot log you on to this domain because the system's
computer account in its primary domain is missing or the password on
that account is incorrect

as well as this from my /var/log/samba/machinename.log

[2003/03/24 12:32:51, 0] smbd/password.c:authorise_login(863)
  authorise_login: rejected invalid user nobody

every time I try to log in with a valid user name.  If i try an invalid
username, nothing shows up in the log file. It seems that my users are
all being mapped to the guest user nobody.  Here is my global section of
smb.conf

[global]
        ;Basic Server Settings
        netbios name = PDC
        workgroup = SMBDOMAIN

        ;Act as domain and local master browser

        ;User home directory and mount drive
        logon drive = H:
        logon home = \\%L\%u

        ;specify the logon script located in the netlogon share
        logon script = "wkix32 logongui.k2k"

        ;automagically add machine accounts

        ;Log location and size

        log file = /var/log/samba/%m.log
        max log size = 1000

        ;sync unix/samba passwords
        unix password sync = Yes
        passwd program = /usr/bin/passwd %u
        passwd chat = *New*password* %n\n *Retype*new*password* %n\n

        pam password change = yes

        ;performance options
        socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

        ;use both NICs
        interfaces = 192.168.1.5/24 192.168.1.6/24

        ;default share values
        create mode = 0770
        directory mode = 0770
        valid users = @is root
        writelist = @is root

Thanks for any help in advance.
