I have found that the occasional webpage will disconnect (seen in attached picture). Can this be caused by DNS lookup issues?
If so, where do I look on the domain controller for these issues? (I mean, specifically as I have looked within the reverse and forward lookup zones, and I'm a bit over my head on this one)
Also, I have noticed that when the browsers do what is seen in the image, pressing F5 (refresh) typically makes the page work (nearly 100% of the time).
