erro in joining domain

I installed an vista business version 23 bit on a P4 3.06 Ghz pc with 2GB
ram with evga gt6200le graphics. it was successfully installed and running
at a decent speed. However when I tried joining to the domain, I got error:

network's administrator, notify the administrator that you received this
information, which has been recorded in the file
C:\Windows\debug\dcdiag.txt.

The following error occurred when DNS was queried for the service location
(SRV) resource record used to locate an Active Directory Domain Controller
for domain abcsys.local:

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.abcsys.local

Common causes of this error include the following:

- The DNS SRV records required to locate a AD DC for the domain are not
registered in DNS. These records are registered with a DNS server
automatically when a AD DC is added to a domain. They are updated by the AD
DC at set intervals. This computer is configured to use DNS servers with the
following IP addresses:

129.168.123.193
129.168.123.254
129.168.123.191

- One or more of the following zones do not include delegation to its child
zone:

abcsys.local
local
.. (the root zone)
