Oracle 11i Post Installation blues

Hi,
Can someone please help with any insight? I installed 11i, and everything went fine.

If I access the 11i, it takes me to the home page ( Oracle applications rapid install Portal), with links to login to (1) 11i Home (2) Apps logon links, (3) Machine Admin Scrips, (4) 11i Online help.

I choose 11i login, then I get the message "Http 404" This error (HTTP 404 Not Found) means that Internet Explorer was able to connect to the website, but the page you wanted was not found. It's possible that the webpage is temporarily unavailable. Alternatively, the website might have changed or removed the webpage.

Can anybody PLEASE offer any advice?

Thanks
