Unable to connect to Visual Studio's Localhost Web Server

This Problem occured when I was trying to compile ASP.net in VS 2005. I tried for 2-3 hours tyring every possibilities like changing browser settings, turning off windows firewall but nothing works. At last I found in some forums that it might be the problem with the file WebDev.WebServer.exe which comes with the .net framework. Then I copied WebDev.WebServer.exe from other machine and replace it and it worked. my gosh ! the file was corrupted.
