Connecting to internet using broadband

I am currently a broadband user connecting to internet using IE6. HOwever, I have problems accessing certain sites e.g. Hotmail, Yahoo Mail. The sites just won’t load.

Also, when retrieving mail with OE6, I received this error message :
“A time-out occurred while communicating with the server. Account:’pop3.streamyx.com’, Server:’pop.streamyx.com’. Protocol:POP3, Port:110, Secure(SSL):No, Error Number:0x800CCC19”

And when I connecting to MSN I received this error message :
“We were unable to sign you in to .NET Messenger Service, possibly because of a problem with the service or with your Internet connection. Please make sure that you are connected to the Internet. 0x81000301”

Please assist to resolve these.

Thanks lots.
