The MCSE 2003 still exists, however, its value is somewhatin question due to the age of Server 2003/WinXP. You could finish the MCSE by taking exams 70-293, 70-294, 79-297 or 70-298, and an additional elective from
this list.
The MCITP Server 2008 enterprise Administrator requires taking/passing five exams, and all information can be found
