Folder comments are not supported in XP except as a compatability thing (ie folder comments set by older versions show in XP).

Older versions set the folder to Read Only or System and put a file called Desktop.ini with the following lines.

[.ShellClassInfo]
InfoTip=An optional description for the folder that displays in a pop up tip and web view when selected
