He has a legitimate reason to ask this. Windows 2000 MCSEs could bypass MCSA 2000. If you look at Microsoft's site, there are a ton more MCSEs than there are MCSAs. The certification path for MCSE 2003 is different as all MCSEs will also be MCSAs, especially in your case as MCSE 2000 is an elective for MCSA.
I wonder is there is a type on his orginal post and he is referring to the MCSE 2000 and not the MCSE 2003.
