Programatically change Administrator Password?

We have a lot of PCs in our NT network. Actually every PC should have the same administrator password, which the user doesn't know. But over the years, the PC were delivered with different passwords. Now we need a routine to change the passwords automatically to something we want. Each PC should have the same password, because of some installations, which need a hidden admin-login, for example. Furthermore it will be reasonable to change the password from time to time.

The changing routine should work without user interaction during startup. We are thinking about writing a (Delphi?) programm and starting it via autoexec.nt

Any ideas, hints, difficulties or solutions to this?

Would changing the password over the network via a batch script be acceptable?  If so download the follwoing utility:
and create a batch file as follows:

====== BATCH FILE =====
@echo off
if "%2"=="" goto error
if not exist %1 goto nofile
del %2
REM the text between these remarks is all on one line.
for /f %%m in ('type %1') do cryptpwd.exe -m \\%%m -u Administrator -P newpassword >> %2
REM the above is on one line.
goto done
echo Usage: pswd.bat wksnlistfile outputfile
goto done
echo Input file "%1" does not exist.
===== END OF BATCH FILE ====

You'll also need a file containing a list of all the workstations/servers that you want to change the passwords on.  Pass this as a parameter to the above batch file:

==== Wksn List file ====
. etc
==== End of Wksn File ====

When the script has run check your output file for errors.
You can then run this script as often as as required.
