I am having a problem with my new Windows Server 2003 DHCP updating DNS
entries on my DNS server.
Environment: 3 DHCP servers 2000 (not on DC's), 3 DNS servers 2003
(integrated on DC's), 1 DHCP server 2003 (not on DC) upgraded. DNS
zone update set to allow unsecured. DHCP set to "Always dynamically
update DNS..." and "...for DHCP clients that do not request."
Problem: New W2K3 DHCP server does not update its DNS server with
client names and IP's. Actually, after DHCP service is started, it
will successfully update DNS, then some failures will start occuring,
after about 20 min 10% are failures, by 30 min 80% are failures,
eventually 100% are failures.
DHCP Log entries look like the following:
Success Type
30,DATE,TIME,DNS Update Request,x.x.x.10,computer1.mydomain.com,,
11,DATE,TIME,Renew,10.x.x.x,computer1.mydomain.com,MAC ADDR HERE,
32,DATE,TIME,DNS Update Successful,10.x.x.x,computer1.mydomain.com,,
Failure Type
30,DATE,TIME,DNS Update Request,x.x.x.10,computer2.mydomain.com,,
11,DATE,TIME,Renew,10.x.x.x,computer2.mydomain.com,MAC ADDR HERE,
31,DATE,TIME,DNS Update Failed,10.x.x.x,computer2.mydomain.com,2,
Anyone have an idea why my DNS updates only last about 1/2 hour without
restarting DHCP?
Thanks, Wayne

What is the Service Pack level of the server?
Any events in the event log?
There is a PreSP1 Hotfix that may be close to your issue. Although, in
the
symtoms describe the issue beginning after several days.
A "DNS_ERROR_TRY_AGAIN_LATER" error message is logged in the DHCP
activity
log on Windows Server 2003
http://support.microsoft.com/kb/872782/
This hotfix is included in SP1.

Thanks for the quick reply Kevin,
Both DHCP and DNS servers are W2K3 SP1.
No negative event log entries.
I will check the articles you suggested and post again.
Thanks,
Wayne

I checked the articles.
http://support.microsoft.com/kb/872782/ states version of DNSAPI.DLL
should be at least 5.2.3790.206 on the DHCP server, mine is
5.2.2790.1830 - so I think we are good in that regard.
I upgraded another of our DHCP boxes to 2003 2 days ago (same
DNSAPI.DLL ver.) - no DHCP to DNS registration errors.
Differences between the DHCP servers:
1.) First box was New 2003 box with DHCP import from 2000 box. Second
was 2000 box upgraded to 2003 then, import into New 2003 box.
2.) Second DHCP box runs about 1/10 the DHCP to DNS volume.
3.) Each DHCP box uses a different Primary DNS.
I am considering, pointing the First DHCP box to the Second DHCP box's
DNS.
Anyway, I am open to any suggestions,
Thanks, Wayne
******************************************************************************
09/19/2006 - Just wanted to send an update.
I found the source of the DHCP to DNS problem we were having.
As it turns out, I was concerned with the DHCP to DNS updates on our
main subnet and had checked that subnet to make sure it had a reverse
lookup zone in DNS - another subnet was created that did not have a
reverse lookup.
The configuration in DHCP for the new subnet was set to add a reverse
to DNS and that reverse zone did not exist, so errors occured. The
strange part is that the missing reverse in one DNS zone caused the
DHCP requests to DNS for the other zones to fail as well (a few
requests at first then eventually all).
When the reverse was setup for the new zone, the errors were reduced
and eventually went away.
