New to the Community, this forum and, probably embassed to say, to home computing (hence a bit of a novice at solving problems).

I'm running Windows XP and recently switched over to Firefox from Microsoft IE. Strange thing has occurred in the past week or so. Firefox and MIE both refuse to link into any web site in any way associated with NASA (National Aeronautics Space Agency). Firefox attempts for a while then load error message appears saying "Server not found". IE comes back with "Page not found". URL all correct.

Attempts to link to any site with a NASA association (even the local Canberra Space Centre) also result in same outcome. Access attempts through NASA links on other world space agency sites also fail. It is only the NASA site that I have had this problem with. Frustrating as NASA is one of my favorite destinations.

I run scans with Symantec antivirus, Ad Adware and Spybot S&D regularly - no problems picked up here.

Any clues fellow Daniwebers?
