I am developing on Windows Server 2003 with VSTS 2008 + C# + .Net 3.5 to develop a console application. The console application is used to get the content of some URL and analyze its content.
I find a strange thing, my computer can access any URL (get page content) either in programming way or from browser. But except *.microsoft.com (e.g. www.microsoft.com, update.microsoft.com) -- from both my code and the browser, the page cannot be opened. I am very confused. Any ideas how to check the root cause? Any tools/settings which could be used to block this special domain?
I tried with Firefox and IE, the same issue. I am wondering whether some global settings which block accessing to some domains? I use the same network cable on another computer in the same room, and microsoft.com can be accessed.
thanks in advance, George
