Slow Internet Connections

[zukinx]

We have a small network with two Windows 2000 servers both acting as domain controllers. One is also a DHCP server, the other provides remote access for VPN clients.

The internet connection for the office is provided through a DSL connection distributed via a cable/dsl router. In the "forwarders" tab on the DNS servers, the dsl router's IP is listed.

On each client machine, the actual DNS servers' IP addresses are entered rather than being provided by DHCP.

The internet connection is primarily slow when finding a website. If you go to google, eg, it will take forever to go just to google. But then doing a search will be rather quick. However, if you close out or go to another website, it will be slow again coming back to google. More than just the slowness of it not being cached or something, too.

TIA

Check you have deleted the . root zone in your forward lookup, this could be causing slow lookup of domain names hence why once you get the domain name resolved the site goes fast but when you goto a new site it has to lookup it again. Only reason i can think that your DNS is going slow.

The root zone is absent from the forward lookup. I'm not sure if the DNS lookups would have worked at all.

How does the server act when it is on the internet? Windows 2000 server running DNS should be the DNS server for all work stations. Are there any DNS errors in the Event Viewer?

The servers are both slow just like the workstations. No recent errors in the DNS event logs. A couple in the application log:
