Can't access some website from inside FW, but can from server in front of FW

Here's a weird scenario i'm facing recently.

I can't access three website (so far) from the LAN (behind a PIX), resulting in Page Can't Be Found. One problem site is

formatting link
However, I can access
formatting link
is in a different IP range, but not most of the links since it links back to
formatting link
I can ping
formatting link
as well as the others. (I have no problems access other URLS, ie yahoo, google, microsoft, etc etc.)

In a few trials, the top image banner would load, following by a long pause, then the "Page can't be found" error - probably due to timeout.

as the two other sites that I couldn't from the LAN, so it seems it's the FW is doing something weird.

I have tried several systems on my LAN, on different floors and different building, all same subnet (I only have 1), used IE and FireFox; to troubleshoot if it's just an isolated case or throughout - all the same problem loading the page.

There hasn't been any router/firewall changes, nor DNS changes recently, I was able to access adobe.com a few weeks ago. No proxy used. No ACL preventing port 80 traffic, or restricting the problem URLs.

any ideas? thx
