Making the Most of IT support?

wetfeetl33t asks: "On Slashdot, we've seen quite a few stories about employees who are unhappy with their company's IT department, or are seeking advice on how they can whip their company's IT department into shape. So, enough of the complaints about the supposed stupidity of technicians, the incompetence of sysadmins, or the excessive network down time. A better question is: how can users work peacefully and effectively with their IT department and make the interaction between the IT people and other employees as productive as possible?"
