I believe I've set up a machine as a BDC for a Samba PDC and I'm trying to test that. Doc sources are the Samba3 Howto and Samb3 by example. net lookup dc (run on bdc or other samba server)lists 2 IP's that indicate that it is in fact a BDC. net lookup dc 172.21.1.10 172.21.1.30 However nltest on an XP machine reveals: C:\>nltest /dclist:CMT Domain 'CMT' is pre Windows 2000 domain. (Using NetServerEnum). List of DCs in Domain CMT \\SUZY (PDC) The command completed successfully This indicates only PDC (Suzy 172.21.1.30). Furthermore running net lookup dc from the PDC shows:>net lookup dc172.21.1.30 Which do I believe? Here's the config from the alleged BDC: [global] workgroup = CMT interfaces = eth1, lo bind interfaces only = Yes #server string = "Sales" printing = cups printcap name = cups printcap cache time = 750 cups options = raw username map = /etc/samba/smbusers wins server = suzy map to guest = nouser logon path logon home logon drive encrypt passwords = yes passdb backend = ldapsam:ldap://localhost ldapsam:ldap://suzy ldap admin dn = cn=Manager,dc=ptcoupling,dc=com ldap idmap suffix = ou=Idmap ldap user suffix = ou=People ldap suffix = dc=ptcoupling,dc=com ldap machine suffix = ou=People ldap suffix = dc=ptcoupling,dc=com ## for BDC logon script = /etc/samba/netlogon.bat domain logons = yes domain master = no TIA, Larry
