system.net.webexception C# Vista

Question

I have object of type WebClient which successfully connects to web server. But when I run this code under Vista I get system.net.webexception socket error.

Answer 1

I was a bit bewildered by my other program that used sockets directly (port scanner) that worked under XP and failed to work under Win7. I thought that might be the case in this current app, but since I used WebClient - high level class - bewilderment was justified) The problem solved by adding modifying scope in excepion's for my firefall. Thanx for your time.
