Errors Running DCDIAG /test DNS...root hint issue

27/08/2007, 23h56

I have a couple of DNS servers in a child domain that report the following
when I run DCDIAG /test DNS.

This is not a valid DNS server. PTR record query for the
1.0.0.12.7.in-addr.arpa. failed on the DNS server 2002.12.27.33
-----------
This happens for all the root hint entries. The upstream DNS servers in the
parent domain are fine and have the same root hints listed. Any idea what the
problem could be here?

Thanks,
Alex

Hello Al,

Please post the complete dcdiag from one of the servers. I see also a posting
in the AD NG about "Global catalog server communication in Paretn/Child"
Are these the same machines? So please do not switch around in the NG's,
because i think these all belongs together. If you have so many questions,
let's do it step by step to find the good way for solutions.

Best regards

Hello Al,

How is your domain DNS configured, from this dcdiag i can not see any internal
ipconfiguration. Please give some info about the setting in the subdomains
and also the level above.

If you are using an ISP I would suggest you remove your root hints from your
internal dns server and forward all unknown requests to your ISP's dns
server. If you are also having other problems in your domain I wouldn't
even attempt to figure anything else out until you clean up dns. Poor
configured dns is the problem for a lot of AD administrators.

Paul Bergson [MVP-DS] Messages: n/a Hébergeur:	Re: Errors Running DCDIAG /test DNS...root hint issue If you are using an ISP I would suggest you remove your root hints from your internal dns server and forward all unknown requests to your ISP's dns server. If you are also having other problems in your domain I wouldn't even attempt to figure anything else out until you clean up dns. Poor configured dns is the problem for a lot of AD administrators. http://support.microsoft.com/kb/291382 -- Paul Bergson MVP - Directory Services MCT, MCSE, MCSA, Security+, BS CSci 2003, 2000 (Early Achiever), NT http://www.pbbergs.com Please no e-mails, any questions should be posted in the NewsGroup This posting is provided "AS IS" with no warranties, and confers no rights.
