DNS problem when I first instal Active Directory on Win2003

When I was installing Active Directory in the first time (1st Domain
Controller in the forest), when it reached DNS testing and installation, it
said:


The SOA query for _ldap._tcp.dc._msdcs.ExchangeLab.com to find the primary
DNS server returned:
DNS server failure.
(error code 0x0000232A "RCODE_SERVER_FAILURE")



Is there expert can help me? Before I installed Active Directory, DNS has
been installed (the zone name is ExchangeLab.com). But I haven't configured
the setting of DNS. Nothing has not been touched on DNS.


My static IP is: 192.168.0.100
Subnet mask: 255.255.255.0
Default gateway: 192.168.0.5 (Linksys router)
DNS: 192.168.0.100 and 192.168.0.5

Router is attached to the high speed modem. High speed modem is connected to
ISP

Then one presumes you (already) have TWO INTERNAL
DNS servers holding that zone ExchangeLab.com.

The zone (on the Primary) needs to be set to allow Dynamic
Updates for AD-DCs.

This zone should be completely isolated from any
EXTERNAL zone (best left at the Registrar) for the
same name.

Separating internal from external zones with the same
name is called "Shadow DNS."

You must add all EXTERNAL resource names to the
INTERNAL server manually.

Pretty much irrelevant.

The error is caused by you having your routers IP for the Alternate DNS
server in TCP/IP properties. You cannot use any DNS server IP in any
position that does not support the AD domain. Since your router forwards to
your ISP, one must assume there is no way your ISP knows anything about your
AD domain which the DC registers its records in, which is why your getting
the errors in your event log.
You can configure your local DNS to forward to your router, but none of your
AD domain members, including the DC should use your router for DNS.
