How can I reset local administrator password for a bulk group of machines? (>700), I read some methods but am not sure if they are up to date? we have native windows 2003 (no Windows 2008or vista).

Thanks for any help,

using start up script in Group policy>
write a batch file >>>>net user administrator (password)

you may use windows resource kit tool cusrmgrto run this script :
-create folder and copy cusrmgr to this folder.
-create in this folder file name it " change.bat"
-computer list should be placed in a file call it " names.txt"
replace 12345678 in the script with your password

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objoutputFile = objFSO.OpenTextFile ("change.bat", 2)
Set objinputFile = objFSO.OpenTextFile ("names.txt", 1)

Do Until objinputFile.AtEndOfStream
    strComputer = objinputFile.Readline
objoutputfile.writeline ("cusrmgr  -u   Administrator -m \\"&strComputer&" -P 12345678 ")
Set objShell = CreateObject("Wscript.Shell")
objShell.Run _
    ("%comspec% /K title Change PWD |change.bat"), _
        1, TRUE
You can also us the net dom command and create a batch file like this:
  1. create a text file containing all of the computers you want to perform the task on remotely
  2. use the following command below to rename the computers
  3. For a full explanation of the netdom command, go here http://support.microsoft.com/kb/298593
ÿÿÿÿFOR /F %1 IN (userlist.txt) do "netdom userd:domainname\administrator_id  /passwordd:* /usero:local_admin*

Open in new window

Hi romari,

by doing that batch script which contains "net user administrator (p455w0rd)"
is it actually applied to the Computers domain or do you have to create custom OU and create GPO and make it as Startup script applied to the computer ?
