Now What??

I’ve passed both the A+ and Network+ certification and planning my next move.I’m wondering if I should pursue another CompTia entrance exam or move on to Microsoft or some other stuff? I don’t want something short lived and I want a certification that has serious backbone. I know there are loyal camps out there as well as “Get as many certifications as possible” types. Currently stuck in an all microsoft environment. Advise please??…Be nice:-) Thanks in advance…
