Hello, Just wondering if there is away to look at the cache of the built in DNS on an ISA server. There is a site that users can't get to, but if I by pass the ISA server it works fine. I figured out if I by pass ISA the IP address if different then if I use the ISA server. So I believe the built-in DNS servers' cache has the wrong IP and just wondering if I can go clear the cache. If not I clear the DNS cache off-hours and reboot the server. I have a script to clear the DNS, but it will take down the ISA services to do it, so have to do it off hours. Thanks. Dan
