What you will probably run into if you mean you want to set the
account to a known, usable password, whether the same on all
of the machines (not the best plan in my view), the same on sets
of machines with there being so many sets your machines are
divided into, or unique per machine, is keeping track of which
machines were available and had the account successfully set
to the new password.
One approach is to use an indicator, like some reg key or file
that only admins can create/delete. Then, your remote process
checks if the indicator exists in correct state, and it not then it
sets the password to new value. Alternatively, you can track
the change state centrally, as in database. The method used
will depend much on how you change the pwd, whether with
something like a WMI script, pspassword, machine startup
script, etc..
