Posts in board are missing

We have two subscribers with problems:

mystery deepens. Found when I go to http://bearinsider.com/forums/forumdisplay.php?8-Men-s-Basketball through Internet Explorer, I can reach all areas except the posts by fans in the mens basketball--can see all the other areas--and can reach recruits, roster,etc. in the mens basketball section--just no posts.

Just found out that if I go through my AOL Search to bearinsider.com, I can reach all areas of bearinsider, including the posts on mens basketball. Just a little more awkward, and still do not know why internet explorer refuses to let me see posts

I went to two different WIFI locations and neither showed the threads on the Men's Basketball Forum. Football works fine. The fact that my wife's computer does the same has me stumped.

***

I told both of them to power cycle modem and router. That apparently didn't work. Told them to use the link I posted. That didn't work.

***
What else can I tell them?

Any ideas how to solve the problem?

Thanks
