IIS issue

I just installed IIS on my windows xp pro machine and when I try to access a
website on the local IIS server, I get the following error message:

"You are not authorized to view this page"

I have enabled "Anonymous access" inside Directory Security option of IIS
and I also granted full NTFS permissions to all users so that the IIS root
directory is readily accessible. However, I am still not able to access any
website that resides on the localhost.

Please help.

Thanks.
JessIs this a SQL Server question?
