[Closed] DNS client problem

Currently i have got 10 winxp computers(all different specs) in the office unable to surf the net and all of them have the same symptoms. Here is the list: All of them can ping the singnet dns All of them cannot resolve the dns to ip IE cannot browse both ip and dns methods. I have brought my home computer to the office and it can surf. And When I brought the office computers home to surf, it doesnt work. I have checked all the settings on the comps, and it should have worked. Initially i thought was a winsock problem, so I used winsockxpfix. Still it did not work. can anyone help? anyway here is the logfile of one of the comps i have taken.
