All-in-One SharePoint 2003 Portal Server is an unsupported topology

Microsoft’s Sharepoint Portal Server 2003 is an out-dated technology and very few legacy sites should exist. However, since the problem of the unsupported topology is a dead end thread on all sites I’ve been searching online, here is my solution to the problem.
Microsoft article “Description of an alternative topology for SharePoint Portal Server 2003” doesn’t include the all-in-one scenario that doesn’t use the MSSQL engine coming with the portal setup.
To install a regular MSSQL instance on the same machine that you are installing Sharepoint 2003, you simply have to use an MSSQL server alias to call the server by a different name:

This tricks Sharepoint 2003 into thinking it’s talking to a remote database server. When you setup up the farm, use the alias instead of the server name to perform the gimmick.
Hope this still helps someone.
