I have just finished reconfiguring our internal network, we now have 2x DC's and DNS servers and 1x Exchange Server. All servers run Windows Server 2003 R2 Standard Edition.
On all of the clients, except for the servers websites take a long time to load in Internet Explorer. When you type the URL in and hit enter, there is a pause of 15 - 30 seconds before the site loads, once a site has loaded other pages on that site load quickly, its just the first load that takes its time.
If you then close IE and open it, and try to go back to the original site, you get the same delay.
This doesnt happen on the servers. I have DHCP running and it maps the 2 DNS servers to each client.
Any ideas why this is happening and what I can do to prevent it ?
