Not exactly the information you want, but this could help. Have you looked at the addusers.exe that Microsoft supplies with the resource kit? You can insert users into W2K AD with it and assign a default password for all users. I extracted my users for my NT 4.0 domain into a txt file, used the addusers.exe, pointed it to my txt file with all the users names in it, and set the default password for all users. I uploaded 275 users in 5 minutes. Maybe this could help?
