Active Directory Domain Slow internet response on first page lookup.

Posted on 2008-11-12

I have a client that has  a Server 2k3 AD domain where the DC is also the DNS and DHCP server for the Domain.  It has two NICs inside, one going to the switch, and one going to the network.  I'm having a problem with the internet.  When I start internet explorer and type in a web address, there is about a 10 second delay from the time I hit enter, till the time anything starts loading on the page.  On the one computer that's out of the domain, the internet load times are great.  Could there be a setting in the forwarders or something that is timing out before re-routing the query to the correct DNS?  Ping times are instantaneous and network transfers are great, it's just the internet.  Please help.

    Are you using some proxy?

    After the DNS server forwards the query to the forwarder with the first IP address, it waits a short period for an answer from that forwarder (according to the DNS servers time out setting) before resuming the forwarding operation with the next IP address. It continues this process until it receives an affirmative answer from a forwarder or the DNS timeout is reached. Try to check forwarders order and configured timeouts in DNS server properties / forwarders.

    Thanks.  THat was it.  The Primary DNS forwarder was sending queries to a bogus DNS.
