I havnt started my MCP's yet but i have done A+ and am going to do the NET+ next. Although i have a lot of experience in Windows Server 2003 (70-290 is what i want to do) i wouldnt dismiss the new OS/s. on that note the Windows Server 2003 exams (In my opinion) are still worth doing. Corporations / Companies still use Windows NT / 2000 so 2003, so the current exams should still be in by 2015. It may also be worth knowing these exams before anyway, its more than likely it covers the same stuff but requires more because of the new features it offers (200 so start fresh and advance to the new exams after the available ones (Thats MY opinion anyway) i also quote "Dont try to RUN before you can WALK"
