whats next after Desktop Engineer?

If i want to start specializing in some technology, what is a good step after desktop support? Just wondering what many of you have looked for after a desktop sup job, did you move to a Jr-Mid level sys admin position, or something different.
when one is the, the one will be the being of willing to be the one.

From where you are pref go to either a jr sys admin or jr network admin position then diversify further from there. The reason most people go sys admin before the others is it shows you a little bit of everything and if you want to keep doing sys admin stuff that's fine too, you just don't make as much money in the end.
What do you like about the aspects of desktop support? Have you played around with security or a router before?
