Internet Explorer V6SP1 won't connect to certain websites

[jacalynhh]

I am unable to connect to certain websites. It appears to
be some government sites or those that are somewhat secure.
At one time about 1 year ago it had something to do with
my system searching for a proxy server? Does anyone have
any ideas?
Thanks

Start here look for your exact error message, and make use the articles
cover secured sites.
