Hi,
Even though Internet Explorer 8 is installed on your Windows Home Server you should avoid using it. Internet Explorer will be running in a locked down mode and various functionality such as Javascript etc will be disabled by default - this will mean a lot of websites will fail to display or work as expected.
If you want to gain a bit more functionality in your console without having to use the remote desktop then there is an Add-In called "Advanced Admin Console":

Cheers,
Al
