[Samba] can mount share, cannot join domain

[jason kawaja]

i am not using ldap.  samba 3.0.7 on sparc solaris.  winxp pro client.

[global]

        netbios name = bunny
        workgroup = ecel
        time server = yes
        security = user
        encrypt passwords = yes
        wins support = yes
        domain master = yes
        local master = yes
        os level = 65
        domain logons = yes
        logon path = \\%L\%u\.win_profile
        logon script = logon.bat
        logon drive = D:
        logon home = \\%L\%u\.win_home
        add user script = useradd -d /dev/null -g 100 -s /usr/bin/false %u

[netlogon]

        path = /usr/local/samba/lib/netlogon
        writable = no
        browsable = no

[homes]

        comment = Home Directories
        browsable = no
        writable = yes
        valid users = @student @despot
        invalid users = @other @sys @adm @uucp @mail @tty @lp @nuucp @staff \
                        @daemon @sysadmin @bobody @noaccess @nogroup @nofiles @qmail
        max connections = 80

drwxrwxr-x    2 root     other         512 Oct  8 13:21 netlogon/

when attempting to set/join domain from My Computer -> Properties, a
window pops up asking for username password and i enter root along with
the smbpassword for the root (uid=0) account.

then an error box saying "The user name could not be found." is
displayed.

i can mount a share using a non uid=0 samba account to this client.

ideas?
