What could cause a site to generate a DNS error one minute in a browser then in another resolve to the correct website? The site has been configured in an identical manner to that of other sites which never experience this problem.
possibly a bad secondary DNS server that does not have all the proper DNS entries ?? So when your primary, which I assume is on the RAQ was not the one that was searched, and the secondary, on another machine, was not setup with that site properly or at all - thus, the site won't be found. Just a thought.
