Removing Windows SharePoint Services 3.0

As Sharepoint becomes mainstream, sometimes is nice to remember the little things. Recently we had a case where we had to do just that. We removed Sharepoint Services 3.0 and reinstaled it, only to notice the same info on the webpage. We did a little digging and came across an article from Microsoft pointing out that when removing Sharepoint Services 3.0, you have to manually remove the Windows Internal Database. With this version, there’s no way to remove it through the GUI and no user notification, so you have to use the msiexec.exe command to do it.
If you are running an x86-based edition of Microsoft Windows Server 2003, use the following command line to remove Windows Internal Database from the computer:
msiexec /x {CEB5780F-1A70-44A9-850F-DE6C4F6AA8FB}
CALLERID=ocsetup.exe
If you are running an x64-based edition of Windows Server 2003, use the following command line to remove Windows Internal Database from the computer:
msiexec /x {BDD79957-5801-4A2D-B09E-852E7FA64D01}
CALLERID=ocsetup.exe
