wild. let me get this straight.
broadband installed.
open IE, and type in
http://www.cowboyszone.com
you get their "host" page? (can you provide a link to what you do see?)
but if you search on it and click a link, it goes through?
firewall possible but if it were blocking traffic i'd think it would do it directly or indirectly as port traffic is just port traffic. if blocking any content, it would do it regardless of how it came through, usually. definately worth checking because something new seems to be causing the grief, however.
lemme know if i got it right, but this is a bit odd. have you rewritten your MBR lately? >g<
