[Samba] Problem Joining a ubuntu 12.04+samba to a W2k DC

Hello to everybody in the forum.

I am trying to join a ubuntu server as a member of a domain controlled 
by a Windows 2000 Server.

When i execute the join the system return de followin error:

sudo net ads join -U administrator
Enter administrator's password:
Using short domain name -- FAMILY
Joined 'CHILD-SERVER' to realm 'Family.local'
net_update_dns_internal: Failed to connect to our DC!
DNS update failed!

Can anybody help me? Any ideas?

Sincerely,

Carlos

[Samba] Problem Joining a ubuntu 12.04+samba to a W2k DC

Hai, 

Why are you using an IP blok which is reserved. 
I suggest you first change to a private range and not a public range or do you
own this range..
This is asking for problems.. 

I suggest, you try with this:

1) check time on both servers, and set te same. 
2) The realm must be in uppercase or you will get a 
	?Cannot find KDC for requested realm while getting initial credentials? error
(Kerberos is case-sensitive!).
but i see all CAPS in your config, but not with the join. 

join with :  ( this is a join as DC, but look at this and what you typed. 

sudo samba-tool domain join FAMILY.LOCAL DC -Uadministrator --realm=FAMILY.LOCAL

change in your hosts file :
127.0.0.1 CHILD-SERVER CHILD-SERVER.FAMILY.LOCAL localhost
TO 
127.0.0.1 localhost localhost.localdomain localhost.FAMILY.LOCAL 


and you can try, below, but should not be needed. 
krb5.conf 
[libdefaults]
         default_realm = FAMILY.LOCAL
         ticket_lifetime = 24000
         clock_skew = 300
	   default_etypes     = des-cbc-crc des-cbc-md5
	   default_etypes_des = des-cbc-crc des-cbc-md5
