I need to Add a Domain User to a Domain Group (that I manage).

I want to do it programmatically as I have about 300 or so users to add. I also want to simplify maintenance as adding future users via our company's normal process is... not very efficient.

I use VB.NET 2010.

Searching the internet I see lots of Active Directory stuff. We have Active Directory on our Network, but I've never used it and don't really even know what it is or if I can access it. I'm looking into it more, however thought I would pose the question here in the mean time.

Thanks for any help.
