D&D Dungeon Master tips?

I'm the DM in my D&D group, and we haven't been able to play in a while (9-10 months) due to school, work, and other distractions. We finally are getting a chance to play again, and I'm afraid the players and myself may have become a little rusty at playing. Does anyone know any tips on how i can get everyone back to there old D&D playing selves?
