    The DNS server encountered an invalid domain name

    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.

    Re: The DNS server encountered an invalid domain name

    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
