I am behind a sonicwall TZ150. Mutiple systems that run through the SWTZ150 are showing this same exact message. Here is how it shows itself. I get on the web (lets say to yahoo.com) using Mozilla (happens with IE too). At some point a few minutes in, if I refresh on the yahoo site, it gives me this STRANGE message

Our IT guys have checked the SWTZ150 and the Qwest DSL Modem (Motorola 3347) and can find nothing in conflict. If I by pass the SWTZ150, and just plug the network cable directly to the modem, and flush the dns's and cookies, etc, then Yahoo comes back. This isn't just isolated to Yahoo, since other sites show the same thing. Yahoo is just an example.
