Hi Group, I have a nasty problem keeping me busy for some time now, I have a samba3 server on Solaris10 who has worked for several years with win98 clients. Now we want to migrate to XP and the domain part is giving me trouble. I am rather new to windows XP and domaining so be patient with me please. My smb.con looks like this : # Samba config file created using SWAT # from 192.168.10.10 (192.168.10.10) # Date: 2006/10/09 22:43:09 # Global parameters [global] server string = Samba Server workgroup = WORKGROUP interfaces = 192.168.10.10/24 bind interfaces only = Yes null passwords = Yes passdb backend = tdbsam guest account = sirtm passwd program = passwd log file = /var/adm/log/smblog.log.%m max log size = 5000 time server = Yes add user script = /usr/sbin/useradd %u delete user script = /usr/sbin/userdel %u add group script = /usr/sbin/groupadd %g delete group script = /usr/sbin/groupdel %g delete user from group script = /usr/sbin/userdel %u %g add machine script = /usr/sbin/useradd -d /dev/null -s /bin/false %u logon script = %U.bat logon drive = I: logon home = \\%N\%U\profile domain logons = Yes os level = 240 preferred master = Yes domain master = Yes wins support = yes nameresolve order = lmhosts hosts wins dns proxy = No ldap ssl = no admin users = root, sirtm, administrator, Administrator printer admin = +staff hosts allow = 192.168.10., 192.168.20., 127.

My Soalris server is DNS server as well, I am pointing this out here as I read articles on the web that claim you need some SVC records in your DNS to get MS clients to discover who is the Domain master, and that's exacty where my problem lies. When I want to add a XP client to my domain, it claims it is unable to find the Domain master, The message windows XP gives: The following error occurred when DNS was queried for the service location (SRV) resource record used to locate a domain controller for domain WORKGROUP: The error was: "DNS name does not exist." (error code 0x0000232B RCODE_NAME_ERROR) The query was for the SRV record for _ldap._tcp.dc._msdcs.WORKGROUP Common causes of this error include the following: - The DNS SRV record is not registered in DNS. - One or more of the following zones do not include delegation to its child zone: . (the root zone) For information about correcting this problem, click Help. And this is where I am stuck for some time now, I have added the SVC records from a posting on the web from some time ago, but the syntax is from a linux BIND version that my Solaris system does not understand. Furthermore I can't understand the need for this SVC records, as they point to ldap ports 389 and I am not running LDAP on my server. Can someone point me in the right direction ? If more input or log files is needed, pls let me know. Regards, Sirt
