You can take 70-284 without taking 70-291 But you cannot get your MCSE2003 without taking 70-291
Exam 70-064: Implementing and Supporting Microsoft Windows® 95
Exam 70-067: Implementing and Supporting Microsoft Windows NT Server 4.0
Vex is correct,
You don't "need" 70-291 for this.
But it will help you pass this one.
Since there is some overlap between the 2(and others as well)
