[Samba] DNS-error from one machine when trying to join domain

[Huyth Jenssen]

Hello again.
I finally managed to setup samba as a PDC and I was delighted to see that it
actually worked this time, thanks to a few people here on the list. I could
join the domain from the a computer running XP but I'm having some trouble
when I try to connect from another computer. I get the following message;

"A domain controller for the domain could not be contacted
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.DOMAIN NAME
Common causes of this error include the following:
- The DNS SRV record is not registered in DNS."

My smb.conf is:
[global]
        workgroup = AE.LOCAL
        server string = %h server (Samba, Ubuntu)
        obey pam restrictions = Yes
        passdb backend = ldapsam:ldap://127.0.0.1
        passwd program = /usr/bin/passwd %u
        passwd chat = *Enter\snew\sUNIX\spassword:* %n\n
*Retype\snew\sUNIX\spassword:* %n\n *password\supdated\ssuccessfully* .
        syslog = 0
        log file = /var/log/samba/log.%m
        max log size = 1000
        add machine script = /usr/sbin/smbldap-useradd -w "%u"
        logon script = logon.bat
        logon path = \\%N\profiles
        logon drive = H:
        logon home = \\%N\%U\data
        domain logons = Yes
        dns proxy = No
        wins support = Yes
        ldap admin dn = cn=admin,dc=ae,dc=local
        ldap group suffix = ou=groups
        ldap machine suffix = ou=machines
        ldap passwd sync = Yes
        ldap suffix = dc=ae,dc=local
        ldap user suffix = ou=users
        panic action = /usr/share/samba/panic-action %d

[homes]
        comment = Home Directories
        path = /home/%S/data
        valid users = %S
        read only = No
        create mask = 0600
        directory mask = 0700
        browseable = No

[netlogon]
        comment = Network Logon Service
        path = /data/samba/netlogon
        write list = @admins
        guest ok = Yes
        share modes = No

[profiles]
        comment = Users profiles
        path = /home/%U/profiles
        read only = No
        create mask = 0600
        directory mask = 0700
        browseable = No

[printers]
        comment = All Printers
        path = /var/spool/samba
        create mask = 0700
        printable = Yes
        browseable = No

[print$]
        comment = Printer Drivers
        path = /var/lib/samba/printers

I don't know if it helps, but the server and the client that can connect are
both running wireless network cards, and the computer that cannot connect is
not.

Any ideas how I can solve this?
