DNS resolution problem?
Posted on 2006-04-25
Hello, Im having some trouble when users view webpages.
When they try to access a webpage for the first time, it takes quite a few secs to open. Once they are in, it goes smooth (2 load balancing T1s). All te users go through the ISA server, but I dont think thats where the problem lies, since once they are in, it is fine. My ISP indicates that it could be high network traffic, but even when there are no people working, the problem persists.
The external DNS Im using belongs to the ISP. I have configured my DNS to forward DNS requests to the ISPs DNS (in DNS Mgmt. properties -> forwarders). I have also added the external DNSs to the external network card of the ISA 2000 server. Is there anywhere else it should be configured?
All my internal clients have my internal DNS set up in their IP Configuration.
Also, for some reason, I cannot see the ISPs page. I can see all other pages (resolving slowly, but I can). I configured a regular computer with an external IP and it works fine, even seeing the ISPs page.
Any info would be greatly appreciated.
If you request any more info, please post and I will post again.
