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
