Changing windows 2000 passwords

Is it possible to change a users password, either through a registry hack or using acommercial or shareware program.

The company I work for is lookin at changing "adminacc" password on all of our 400 machines due to a change in staff.

Our servers run various versions of netware Netware.

Thanks for any help.

 

If you have Active Directory it is possible via Computer Management.

 

We use all netware servers

Its the local user passwrod we wish to change

 

I tested this to change the local admin password and it worked,
Dameware. You would have to log onto all 400 workstations but it does work.
