I have a MacBook Pro running OS 10.6. There were websites I used to visit without any problems (like www.livestrong.com and gigapedia.com). Then one day (nothing changed hardware or software-wise), I could no longer access these sites from my computer. My friend came over - with his PC - and was able to access it from my network. I was also able to access the sites from my wife's iMac G5 and iPod Touch (same network), but I still cannot access them on my computer using ANY browser (Safari and Firefox). I cannot access the site from anyone's network either --- making me think my MBP is doing something weird with the Network Settings. I keep getting: "The server denies connections. The server might be too busy or might be disabled. Try again a bit later." I have installed Glimmerblocker on Safari and AdBlocker on Firefox, but turning these off does NOT change my results. What do I need to reset or what did I do to cause this? How do I fix this?
