|Do I assume you mean when you launch IE it opens to the page or when you boot your computer IE opens to this page?|
Regardless, if you start your computer and IE opens with the page as the computer boots, go to START>RUN>type: MSCONFIG>OK then click on the STARTUP tab and look through the list of startups to see if IE is set to launch. If so, uncheck the box. Close out and reboot and see it this solves the problem.
If the site opens when you launch IE, then launch IE, click on TOOLS>INTERNET OPTIONS>GENERAL tab. In the HOME PAGE box the address bar will have the URL of your home page. If the web site in question is what is there erase it and put whatever you want there or click on the BLANK tab if you want IE to just open to a blank page.
If either of these does not apply post back.
