Hi,

In our AD architecture we have 4 sites, one DC (Windows 2000 SP4) in each
site acting as Global Catalog in each site and as a DNS server. In Active
Directory Sites and Services we can see all 4 sites on each DC. But in DNS
on each DC we can see only 2 sites (Site1 and Site2). Everything was fine
yesterday. Can someone me with this.
Thank you

Run DCDiag to test your DNS and AD replication quickly.

Then fix any reported problems and consider restarting
the NetLogon service or using "DCDiag /fix" on every
DC after you have fixed those problems.

herb,

I work with Jacques Demers. One of the four DC is a Windows 2003 DC.

I ran NETDIAG /TESTNS and 2 W2K DC come out with this error:

DNS test . . . . . . . . . . . . . : Failed
[WARNING]: The DNS registration for 'syst0101.bellnordiq.net'
is
orrect only on some DNS servers.
Please wait 15 min for replication and run the test
again.
[WARNING] The DNS entries for this DC are not registered correctly on
DNS s
rver '10.212.7.7'. Please wait for 30 minutes for DNS server replication.
[WARNING] The DNS entries for this DC are not registered correctly on
DNS s
rver '10.212.127.42'. Please wait for 30 minutes for DNS server replication.
[FATAL] No DNS servers have the DNS records for this DC registered.

But replication is still OK and DNS records too. The W2K EDC with the 5 FSMO
roles is OK as well as the W2K3 DC.

Ok (but I prefer just running DCDiag with all of the default tests, sending
output to a text file and searching for all WARN, ERROR, and FAIL
notices.)

So some of your DNS is not correctly replicated.

Well, they likely are NOT OK since at least one listed DNS
server (of those NS records in your DNS zone which supports
AD) doesn't have the proper records for this DC.

Do you have any "missing DNS" servers (retired, removed etc.);
I would especially pay attention to any "secondaries".

Also make sure that no one has added any "public only" DNS
servers as and internal DNS server on the internal version of the
zone (if you use the same name internal and external and have
"Shadow DNS".)

Go through the list of NS records in your working DNS servers
and check the replication (traditional DNS or AD-Integrated as
appropriate) on EACH of these.

If some secondary is not replicating (but it used to do so) then
most likely is a messed up zone "serial number" which must
be HIGHER on the MASTER (lower on the secondary).

If that isn't the problem then most likely the master doesn't
permit "zone transfers" to some secondary.

Were it an AD replication problem (AD Integrated DNS) then
you likely would/will see additional errors with DCDiag which
indicate that AD problem.

And again, don't overlook that this might just be a semi-bogus
error where you have retired/removed a DNS server but it is
still listed in the NS records of the zone.
