VB Script for addting users automatically to Exchange 2007 Distribution list

Hello,

I would like to know if there was a VB Script with which I can add users that is the new hires or internal transfers automatically into the Distribution list of their department. Right now it's all manual where in the IT people go into the exchange and add users manually.

But, I want to come up with an automated way to add them to their respective distribution list so that we can get rid of the manual process.

Please it's a real urgency and emergency if I can get a quick reply. I just want to know whether I can automate it or not????

Thank you.
