The DNS server encountered an invalid domain name

Sponsored Links

Hi,

We have a sinlge forest/domain. 2 dcs at data centre. DNS in AD-integrated
and all dcs are gcs. The primary dc dns is configured to provide the dns
service for internet users through the firewall (allowing protocol-
udp/domain). Everything is working fine. No other errors. But we keep getting
the below information events in the DNS event logs.

Please guide, what are these event logs ?

Thanks in advance,

abc.

Hi
Have a look at this link

I hope that the information above helps you.
Have a Nice day.

Hi,

Thanks for reply.

I did check that link before. I have not configured our dns server as
forwarder. As said i have allowed udp/domain in the firewall to resolve
internet dns queries by the server through root hints.

I will have a look at firewall. But there were no such errors earlier, when
we had a seperate dns server, with similar firewall settings.

Thanks again,

abc
