UPS.com tracking with SBS 2003 Server

I am having trouble with tracking packages on the UPS.com website. The page either times out or opens with all windows giving false error on the web page. I set all the security settings according to UPS.com settings, adding the site to trusted and allowing in privacy. This happens on all computers on the network. I have disabled the firewall and anti-virus on the server with the same results. I want to thank everybody for any help. The people don’t want to use third party software to do there tracking. All other websites like Fed-Ex, etc. all work.
