after two weeks i can´t browse certain sites with firefox or with ie:
cnn, fox, abc, aljazeera, panda software, debian.org, google groups, etc.
if i try any of the above sites, after a long wait i get this messge:
"Firefox can't establish a connection to the server at www.cnn.com"

i´m runing XP pro sp2 with nod 32 and outpost pro firewall.
connect to the web trough a modem router.
i´ve checked my system with ad aware, spybot, ewido, a-squared, bit defender online and hijackthis and none found any kind of malware or virus.
i FOLLOWED microsoft instructions to flush dns´s, to reset dns´s...it didn´t HELP....
also checked/ renamed/ hosts file and there is nothing wrong with it....
i´ve another pc sharing the connection since LAST monday and from it i navigate everywhere without any problems!
can you pls. help?
thanks!So you are 100% sure it is the software or configuration it sounds like. Do you have a real Windows CD to reinstall with if necessary? Was a real one used for this installation?well, it looks like a software or configuration problem.
i tested with a different modem/router...
unisnstalled nod 32 and outpost...
and the problem persists.

i´ve the real windows cd and all the fixes installed.
and i wouln´t like to format the drive.

can you pls. advise.
