You can do it using a script and the net user command....
In this example i have used the psexec.exe tool from sysinternals
(freeware) to launch net user remotely (you of course need to be
domain admin to run this...)
In the below example I assume that the computer accounts are in the
Sales OU and that psexec.exe file is in the os path.
**********************
Set objShell = WScript.CreateObject("WScript.Shell")
Set objOU = Getobject("LDAP://ou=Sales,dc=lcab,dc=net")
For each obj in objOU
strSetPassword = "psexec \\" & obj.cn & " net user
Administrator P@ssw0rd"
Set objSetPassword = objShell.exec(strSetPassword)
Next
