As mentioned in your previous thread, DNS is the system that looks up URL and translates them into IP addresses. You could have answered this yourself with a simple search. Google is your friend. (AKA: STFW).

In a previous thread here a similar problem was reported and speculated that it was related to how the DNS servers in question were dealing with IPv6 (most users still use only IPv4 and so don't see IPv6 problems, but some of the software on the Knoppix disc apparently supports IPv6). I know they say that they don't support Linux, but this might be a good thing to discuss with the system admin people. Failing that, I would read through the thread that I referenced you to and see if it doesn't give you some things to try. I can't test any of these myself, since my Internet Service Provider limits me to IPv4 (as does my router). There are many different DNS servers that you have access to, changing the DNS server used may help (this is set by DHCP originally but this setting can be changed, see the thread for details). Also, just using a different browser may resolve the issue.

It may be worth it to you to take notes on what DNS server your system is using when it fails, and check it again later if you find it working again. Your DHCP server may be selecting from several DNS servers, and one might be configured in a way that causes this problem, while others are configured in ways that do not. If you were to report this issue with the IP address of the problem DNS server and the IP address of a DNS server that does not cause the problem to the network admin, and explain the problem, then it is likely that they would correct the configuration of the problem DNS server and you would have to deal with it manually in the future.
