You can permanently remap keys via the registry in Windows 2000/XP. I think the following would transform NumpadDot into the comma key. But since I haven't tested it, be sure to back up the current value of "Scancode Map" from your registry beforehand. Also, after making the change I believe a reboot is required.

Windows Registry Editor Version 5.00

02,00,00,00,\
; 01. Comma sent for NumpadDot:
33,00,53,00,\
; 02. Null Terminator (required) (be sure to change the count at the top to reflect this number)
