Can not access some pages on the Internet

I have a wdw 2k network with 1 domain controller. two unmanaged switches, and DSL connection. The server has has two dual network cards. one is connected to the switch and the other to the dsl modem. I am running dns on the server.

This is my problem: from the server I can access the web and go anywhere including the company web site whitch is hosted on a different location. However, when I go to any other pc in the office I go anywhere in the web but not the company site. we have contacted the hosting site and they say the problem might be on our end. also we are unable to get company email.

I have no idea where to start

Please help

Hi belink,
COnfigure you internal DNS server as the clients DNS server, then enable forwarders on your internal DNS server and set up your ISP's DNS server as "The next port of Call"

Also open your DNS admin console and ENSURE you dont have a "." (full stop) in it, as this will disable DNS forwarding

where ca I make those changes. I have DNS open but do not see. In the client PC I have them pointing to the server for dns and on the server I'm using the ISP DNS server on the second NIC.

I added the isp dns to the clients pc but nothing. remember the only page I can not access is the company's web page all the others work fine

expand the server you are on and right click it, then select properties

>>do I setup "The next port of Call"

youve done it!

>>Ok I enable forwarders and added the isp dns IPs

you need to open the forward lookup zone untill you see your DNS entries in the right hand pane, make sure there is no full stop in there :0)
