You could check the proxy settings for IE under Internet Options\Connections\Lan Settings. If you don't have a proxy server that you use, uncheck the "Use proxy server for your LAN..." checkbox. You can also uncheck all of the checkboxes that either auto detect the proxy, or use automatic configuration script; these would speed up starting up IE, since it doesn't have to look for the proxy server.
