Win2K: managing printers remotely?

Hi there. I have 5000+ machines across ten different physical locations, and I need to find some sort of solution to remotely add or change print drivers for these workstations. We add/move/remove network printers somewhat frequently, and I need to be able to remotely change the print driver and/or ports without physically touching every machine. Is there a reg hack or a script that can automate this process? Obviously, I’m looking for a tool that is native to Windows but would be willing to purchase software to accomplish this if absolutely necessary.
