Weird DHCP/DNS Issue (Server 2003)
Posted on 2006-05-20
Hi, I'm running Server 2003 with DHCP and DNS set up on the main domain controller. I have DNS set up correctly so that all XP clients look at (and only at) the Domain Controller (DNS) server for both DNS and DHCP.
On client machines, I can't access web pages using Internet Explorer. I can't access google.com by typing the URL or by typing in the numeric IP Address in the web browser. However, from the command line I can ping google.com using both the URL and IP address.
On the server there was an Application warning that said that I didn't have a DHCP user set up that would allow DHCP to actively update DNS...so I used the Administrator login to allow DHCP to update DNS. However--I never had to do this before and things worked fine for a few months--Also, even though I added the admin user login to DHCP to allow active updates of DNS; DHCP will no longer automatically create A records in DNS when computer logs onto the domain. So, I hand created A records for the client computers that I'm testing on and they still have the same problems.
Weird thing is, the server itself and one member server can access the internet. However, another Domain Controller (backup DNS without DHCP) and none of the clients can access the internet through a web browser--however they can all resolve domain names at the command line.
Furthermore, client computers can send email and can use Instant Messaging programs like Yahoo Messenger with no problem...but no web sites.
I'm confused as hell...I've already uninstalled and reinstalled DHCP and the issue persists. Is there anything I can do other than reinstall DNS from scratch?
