I have this problem:
I`m using a proxy server,but I can`t get acces to internet,only to email.I was using a program called hopster (www.hopster.com) preview release 16,and even if very slow,the program byoass the proxy and let connect to the web.
It seems that in the server found out and close the exit.
Does somebody knows how can I get the new settings of the proxy server or have some idea to help to get to Internet?
The proxy data is:
prox.sld.cu port 3128.
I will be very,very happy if someone help me.

Try Microsoft technet. You've hardly given enough info for anyone to help you.
