Windows 2000 Professional (Exam 70-210)

Of course, you'll want to check out Dave's Notes first!

The Cramsession Study Guide prints out at over 30 pages, but well worth the read...  I found it helped me quite a bit in my exam prep.  I found the hyperlinks to Microsoft Knowledge Base articles to be helpful.  A recent change to their site is that you now need to log in.  It's free, but you will have to register, which is definitely worth the effort.

CertifyExpress now has a study page for this exam.  You also have to register with them as well.

The official Microsoft Preparation Guide outlines the skills being measured in this exam.

MSExpert has training exams for 70-210.
