MCSA, CCNA at the moment... stopped doing certs a year ago. So many people cheat on them they're almost worthless. I'll probably still work towards my MCSE though.
Got my ITIL v3 and that's it. You don't need certs to succeed in IT, you just need to land a job with a large and well-respected company and then rack up 2 or 3+ years of solid experience proving you can suceed and indeed thrive under pressure in a large corporate environmen. It's worth more than 10 certs.
