I have a problem using IE7 with XP Home. It can’t access Microsoft Windows sites and cannot change homepage in Internet Options even though I am the system administrator. I also Keep getting error codes;http404 with IE7,error #56with Live Messenger and errors #80048820/#80048430 with Ninemsn Premium.
This almost certainly sounds like an Active Scripting problem. We’d suggest downloading and installing the latest Windows Scripting Host.
It’s also possible you have a spyware infection. So running a spyware scan would be a good idea.
Another possibility is Internet Explorer needs reinstalling.
You don’t need to uninstall and reinstall, open the Control Panel and click Add/Remove Programs, or Programs in Windows Vista, and select Internet Explorer.
To right of the selection there are two buttons; change and remove. Click the Change button and follow the wizard to repair the existing installation.
