How can I install SharePoint Team Services with a Microsoft Data Engine (MSDE) database on partitions other than C:?

Install Microsoft Office XP Professional in a minimum configuration (Microsoft Access is the only optional component you need).

Navigate to the shareptsqlx86setup folder of the SharePoint CD-ROM and run setupsql.exe to install MSDE--specify the location for the programs and the database on a partition other than C:.

Navigate to the sharept folder of the SharePoint CD-ROM and run setupse.exe to start SharePoint Team Services setup.

Open the SharePoint administration page and update the Web page you want to use for SharePoint, leaving the database connection information set to the default values (machine=netbiosname; the username and password for the connection are both null).

At the end of the update, you should have a SharePoint home page up and running.

Reboot the machine.

Uninstall Office XP Pro and install the Office suite you'll use on that machine.

If you want to use the C: drive only for system files, you'll have to move the Web site Home Directory before installing MSDE and delete the index catalog named "Web" from one partition and create a new "Web" catalog on another partition.
