Here are the four most common error messages which you might encounter when using Netscape:
Sometimes I have seen intriguing links listed by search engines that, when I first followed them, produced this message. I have successfully figured out where the page moved to sometimes (or perhaps just got lucky!). What I do, if I really want to pursue such a link, is to put my cursor at the end of the address in the Location box and backspace until I get to the *root* address. There have been times that the page had simply moved to another subdirectory at the same site.
(See also Quick Tips: Ready Reference on the Web for tips on decoding URLs.) Most of the time, when you get this message, though, you are dead in the water and might as well write off that link.
As more and more people are on the Internet, some of these DNS computers are getting overwhelmed. If your Netscape has not heard back from the DNS computer within a certain time limit, it assumes that the DNS computer was, in effect, sending a negative reply. This may not be the case. The DNS computer may simply not have replied yet because it was still answering all the other people's Netscape queries from each of their computers.
One way to test whether the DNS computer is being slow to respond is to ask next for something like the AltaVista or Yahoo! Web page. You know that it is highly unlikely that either of these have let anything go wrong with their Web sites.
If Netscape comes back and tells you that AltaVista does not have a DNS entry, you know that it was not a bad link but rather a too-slow DNS computer. If you cannot link to anything, take a break and try again later.
Once this happened to me and I finally decided that the computer at my Internet Service Provider was *down* (or nonfunctional). I could not link to any Web page nor could I connect to read my email. One day later, all was back to normal without my having to do anything. (Evidently, my Internet Service Provider had cleared up whatever temporary problems they had been having.)
Some Web pages are extremely popular. Most Web pages can only handle so much traffic at the same time. It has been my experience that if you get this message, if you are persistent and keep trying the same link over and over, you will eventually get through.
If you have to get an error message, this is the best of the four to get. Most often, after I finally get through and the Web page FINALLY loads, I am favorably impressed with the Web page and readily understand its popularity.
