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