I am having a wierd problem. This is happening site wide. While we are browsing the internet we will click on a link or try to go to a web page and we will get an error that says page can not be displayed. If we refresh or just type in the address again, eventually it will display. Nothing major has changed in our network. We have two internal DNS servers that have forwarders of our ISP's DNS servers. I have changed these once before to see if it helps but to no avail. Could my setting on my DNs server be messed up. Everything was working great a month ago. We do have a webshield from mcafee and a watchguard firewall. We dont have the webshield doing anything except scanning http, smtp ftp and pop3 traffic. nothing has changed on that side for a while. Are there any tests i can try to see if its our DNS servers?
