!@#$ Cannot uninstall the WSS V2 before Portal

Recently try to build some SPS2003 server, after build i have face some problem with the Front end server setting so i think is something wrong with the setting. Decide to uninstall the SPS2003.

click on add remove program then will see wss and sps there, so i think wss is small one then should remove first....#$@#$ after remove the wss then cause the sps unable to uninstall.

now i have 2 solution:

1. follow the complecated change to make it can uninstall and install again..(not sure how is the process from Microsoft)
2. Rebuild server OS . (ha ha, this is my option)

so anyone thinking to reinstall share point 2003, please take note. uninstall SPS, WSS then only ISS. :)
