Your problem is not security related. Just do the following:
1. Click the Tools icon in the upper right corner in IE
2. Click Internet Options
3. In the Tabs section, click Settings
4. Check the box for "Open home page for new tabs instead of a blank page.
5. Click OK twice
That should solve your issue. If it doesn't, post back.
BTW, the reason your custom home page shows up in the Local Computer Zone is
because it is located on the computer itself. If you put a Mark-of-the-Web
(
http://msdn2.microsoft.com/en-us/library/ms537628.aspx) in it you can make
it show up in the Internet Zone. Put this on a line of its own in the HTML
header:
<!-- saved from url=(0014)about
:internet -->
When you next open the page it should show up in the Internet zone.
