Changing Multiple account passwords in N

Hi,

We are doing a network upgrade from Token-Ring to Ethernet this weekend. As part of this upgrade I need to change passwords for about 50 users on the domain to allow our Lan Team to login as these users and test various applications that comeup under the users' profile.

Does anyone know of a utility that will allow me select users from an NT4 Domain and set the same password for them ?

Thanks in advance
