Here's the script that I use to change admin passwords.
It requires the file cusrmgr.exe from the Windows 2000 Resource Kit.
It is a great tool to have for scripting.
You can change global and local groups, etc also!

code:
 
BREAK ON
;DEBUG ON
;========================
;=	Variables To Edit	=
;========================
;Username Note: This should be the local admin account of the remote PC's.
$USERNAME = "administrator"
;Password Note: This should be the local admin password of the remote PC's.
;Special Note: @, %, $ are special characters.
If your password contains them please type them twice in a row.
;EX: "$Test@_$" = "$$Test@@_$$"  Remember, they are inforcing a password scheme now.
$PWD = "yourpassword"
;Required files:  cusrmgr.exe from Windows 2000 Resource Kit
;========================
;=	Do Note Edit Below	=
;========================
IF OPEN (1,"PCLIST.TXT",0) = 0
	$LINEINFO = READLINE(1)
 	WHILE @ERROR = 0
  	? "PCNAME: $LINEINFO"
  	?
		SHELL '%COMSPEC% /C cusrmgr -u $USERNAME -m \\$LINEINFO -P $PWD'
		SELECT
			CASE @ERROR = "0"
				? "Successful"
				SHELL "%COMSPEC% /C echo $LINEINFO,Success>> admin_log.csv"
			CASE @ERROR = "53"
				? "No PC Found"
				SHELL "%COMSPEC% /C echo $LINEINFO,No PC Found>> admin_log.csv"
			CASE @ERROR = "5"
				? "Access Denied"
				SHELL "%COMSPEC% /C echo $LINEINFO,Access Denied>> admin_log.csv"
			CASE @ERROR = "2245"
				? "Invalid Password"
				SHELL "%COMSPEC% /C echo $LINEINFO,Invalid Password>> admin_log.csv"
			CASE 1
				? "Weird Error"
				SHELL "%COMSPEC% /C echo $LINEINFO,Weird Error>> admin_log.csv"
		ENDSELECT
		$LINEINFO = READLINE(1)
		?
	LOOP
$RC = CLOSE (1)
ELSE
	EXIT 0
ENDIF
EXIT 0
I use it all the time. Hope it helps you!
