dcdiag fails - server GUID DNS name could not be resolved


M

Mark

The Exchange 2003 installation pointed me to the dcdiag
utility, which apparently found problems with my DNS
setup. It complains "a6e1e747-5f44-451b-94ed-
26aff4a954e7._msdcs.santaclara.astutonetworks.com's server
GUID DNS name could not be resolved to an IP address" and
to "check the DNS server, DHCP, server name, etc" but
doesn't say what to check for.

DHCP is not running on this machine and when I setup the
DNS, I simply answered a few questions. Since there where
not a lot of questions I expected it not to have a problem.

I've read the Microsoft DNS pages, but can't figure out
what is wrong. I could find no knowledge base article
matching this problem.

The machines name is aruba. When I setup a client to use
it as a DNS server by default nslookup complains that the
domain is non-existant. But when I go into nslookup I can
set to the IP address of aruba and then inquiry about
aruba and get no errors.

[n:\4nt300]nslookup aruba
*** Can't find server name for address 192.168.1.10: Non-
existent domain
Server: dns1-sac.scrmca.sbcglobal.net
Address: 206.13.31.12

*** dns1-sac.scrmca.sbcglobal.net can't find aruba: Non-
existent domain
server 192.168.1.10
Default Server: [192.168.1.10]
Address: 192.168.1.10
Server: [192.168.1.10]
Address: 192.168.1.10


Thanks in advance,
Mark

Remove SBC's DNS from your NIC setup on all machines and point all machines
to the local AD DNS server, preferably should be the DC. The DC should use
its own address for DNS only, unless you have more than one local DNS server
for your AD Domain.

Make sure you have dynamic updates allowed on your forward lookup zone for
your local domain.

I changed the DC to only use itself for DNS, but dcdiag
gives the same error.

Problem still not resolved.

Point the server to itself for DNS. Make sure that the DNS zone allows dynamic updates. Stop the netlogon service then open a command prompt. At the
command prompt type "ipconfig /flushdns" and then "ipconfig /registerdns". Start the netlogon service again. In the forward lookup zone for your AD, check in
the _msdcs.santaclara.astutonetworks.com zone for the existance of a cname record by the name a6e1e747-5f44-451b-94ed-26aff4a954e7. It should be there
now. The data portion of this record should show the name of one of you DCs.

Correction - your suggestion did the trick. It just took
a while to show up.

Thanks

Thanks for the notes on how to clear the DNS cache. It
was working before I got the chance to try it.
