Windows 2000 Active Directory Scripting -- what should I know?

In two days I am going for a job interview for an IT position which will involve doing “Windows 2000 Active Directory Scripting” … the only problem is that I haven’t really done this before, and although I probably won’t get hired anyway, I don’t want to sound like a complete idiot during the interview. Anyone here who does this, and feels like giving me a general overview? How hard is it to pick up (I do have a pretty extensive background, both in scripting languages and NT servers), and are there just a few basic things I should know?
