Not at all. Unless you went to a top school, where you went to school becomes irrelevant after a few years. Where you worked and what you did become much more important.
I would say that after a few years, even if you went to a top-flight school, no one cares. The only lasting benefit is the collection of connections that you made while you were there.
Todd is right. After a couple of years, your school is much less important than what you've done with it during that time.
