Welcome to Seven Forums karmascenic. Do the hospital sites not work with IE9, or is it just "forbidden"? Perhaps if your friend explains his new PC came preinstalled with IE9, and there is NO version or IE8 to download for Windows 7. This will be a problem going forward, wait until someone has Windows 8 with IE10!
If there is just a browser sniffer blocking IE9, then as mentioned, press F12 to bring up the developer tools. Select IE8 under Browser Mode.
