Hello Dennis, welcome to our site :)
Our announcement posted at the top of this forum does state that HijackThis logs should only be posted in our Viruses, Spyware, and other Nasties forum, but I've deleted your duplicate post in that forum, primarily due to the fact that your log shows no indication that malicious infections are the root of your problem. Given that, and the fact that our posting rules prohibit asking the same question in multiple forums, I think this forum is better suited to your question/problem, even if it does contain a HJT log.
It would be good to clarify one thing regarding your problem: is the "find a zip code" link on UPs' site the only link/site where you encounter the "Cannot find server..." messages, or does it happen at other sites as well? If so, please elaborate.
