Gurus,

On a Windows Server 2003 DC, running DNS, had an event log clear of errors.
Until I tried to convert my _msdcs.domain.local zone from standard primary
into AD-integrated with replication to all DNS servers in the forest. When
I tried to do so, the following errors appear.

This one from my DNS log:

Event Type: Warning
Event Source: DNS
Event Category: None
Event ID: 7062
Date: 10/23/2005
Time: 10:44:03 PM
User: N/A
Computer: EBIZ-GATE
Description:
The DNS server encountered a packet addressed to itself on IP address
192.168.1.2. The packet is for the DNS name
"_ldap._tcp.pdc._msdcs.ebiz.local.". The packet will be discarded. This
condition usually indicates a configuration error.

And this one from my System log:

Event Type: Warning
Event Source: NETLOGON
Event Category: None
Event ID: 5781
Date: 10/23/2005
Time: 10:44:07 PM
User: N/A
Computer: EBIZ-GATE
Description:
Dynamic registration or deletion of one or more DNS records associated with
DNS domain 'ebiz.local.' failed. These records are used by other computers
to locate this server as a domain controller (if the specified domain is an
Active Directory domain) or as an LDAP server (if the specified domain is an
application partition).

Here are my vitals.

1) ipconfig /all

2) ADUC domain name: ebiz.local

3) Forward Lookup Zones:

Standard Primary:
_msdcs.ebiz.local
dc
domains
gc
pdc

Standard Primary:
-ebiz.local
_msdcs
_sites
_tcp
_udp
domainDNSZones
forestDNSZones

Reverse Lookup Zones
0.in-addr.arpa
1.168.192.in-addr.arpa
127.in-addr.arpa
255.in-addr.arpa

This error is common at startup if you have only one DC with DNS in a
domain. It is caused from a catch-22 situation, AD cannot start without DNS,
when DNS starts since AD has not started, DNS cannot load the zone.
IF you add a DC, then point the DCs to one other DC and itself for DNS,
should stop this. If you only have one DC use standard primary zones or
ignore the error. Preferably ignore the error because there is no security
on standard primary zones.
