Four MCSE, MCSA Tracks are available. The MCSA fcould be considered as a "Mini" version of MCSE. For instance for Administrators who don't have the need to dig 'deep' into Windows Design and Implementation. However MCSA exams will count towards your MCSE certification. So you still have the possibility to pass the MCSE after the MSCA without having to pass again all the exams.

 

MCSE server 2003 requirements  

Microsoft modify regularly the requirementsor/and the exams objectives. For instance if you are certified in Windows 2000, you will have to upgrade to a Windows server 2003 certification. Requirements to upgrade a W2K MCSE, MCSA  to a Windows 2003 MCSE/MCSA certification can be found by following the links above. Moreover Windows Vista, the (successor of Windows XP) is about to be launched. Obvouisly it will make major changes on the Tracks to accomodate to the new platform Vista. If you already have extensive experience administrating Window 2003 environment, I suggest starting the 2003 Track. I wish you good luck in the long way to get certified Microsoft MCSE or MCSA.
