When you browse to a DotNetNuke website, it displays a DotNetNuke pinwheel icon next to the URL in your browser.  You do not like this icon and you want to replace it with a custom icon for your site.

In order to change the favicon, you will need to:

1)  Log into your site via FTP
2)  Navigate to the HTTPDOCS folder
3)  Upload your new favicon.ico file and overwrite the existing DotNetNuke favicon.ico file.

NOTE:
If you upgrade your DotNetNuke website to a newer version, it will overwrite your customized icon and you will need to repeat the instructions above.
