This may be a dumb question, but have you checked your hosts file in windows
to be certain that a
popularname.com 127.0.0.1 doesn't exist for the sites you wish to visit, put
there by some bug ?
There should be only one active listing unless you added others yourself in
that hosts file.
c:\windows\system32\drivers\etc\ (for example)

If you can ping it by name, that would indicate that DNS is working.
Try pointing a workstation to the ISP DNS, rather than yours. If that
workstation works, problem lies on your DNS server. Since it's DSL and
probably using PPPoE, MTU issues are a possibility as well...

Subject: OT --- Peculiar DNS Problem
Hi Guys, Have peculiar DNS Behaviour. Here is the Detail:
Have a 1700 Series with ADSL Card For Internet Access. Have Windows 2003
DNS Server functioning as a forwarder. The Windows 2003 DNS will forward
the DNS requests, to ISP's DNS Server for internet name resoultion.
Below is a simple topology shown
ISP ------ 1700 ADSL --- Cisco 2950 Switch ------ Windows 2003 DNS
Server
and Clients.
Problem:
The Problem is can't visit most websites.
When I try to ping www.cisco.com, it works fine. If try to visit
http://www.cisco.com, it timesout. However, can visit
http://www.ciscopress.com website. The 1700 Series has firewall feature
set. We are yet to turn on FW functions on 1700.
Any insight is appreciated.
Thanks
