I'd recommend going for CCNA/CCNP (remember CCNA is worth f*** all today) and MCSA/MCSE certifications.
If you'd like something that is generally accepted, and from someone other than the proprietary company's.
Then you should go for some CompTIA certifications, mainly A+ (mandatory), Server+ and Network+.
CCNP I would hope then. CCNA is like the noobs beginner exam. It's not bad, but it wasn't hard, and it never got me anything. In fact, it once got me turned down for a really nice job. They wanted someone exactly like me but without that kind of training because they wanted someone they could teach to do things their way. I just gave them a weird look and left. When non-IT people want things done their way it's usually a bad thing.
