Script to change domain passwords from a list.

I need script to change user password from a list of user IDs and passwords.

I have an excel spreadsheet that has everyone’s names on it with thier user id and “to be set” passwords.

Example:
user id password
rp12345 Rp12345
cd23456 Cd23456
to45678 to45678

and so on.

This is for Windows Server 2003 native activey directoy.

Thanks
