Hi
Yes, if this is an Active Directory domain:
You could do it in a computer startup script (with a GPO) that runs
as part of the boot up process (before the user logs in). It runs
under the system context and has admin rights.
To avoid users being able to read the script where the password is
stored, grant read access only for the AD group "Domain Computers"
to the script file.
As long as the Administrator account name is "Administrator", this
batch file will set the password on the account:
'--------------------8<----------------------
@echo off
net.exe user administrator newpassword
'--------------------8<----------------------
As long as the Administrator account name is "Administrator", this
vbscript will set the password on the account:
'--------------------8<----------------------
sNewPassword = "testpassword"
Set oWshNet = CreateObject("WScript.Network")
sComputer = oWshNet.ComputerName
On Error Resume Next
Set oUser = GetObject("WinNT://" & sComputer & "/Administrator,user")
oUser.SetPassword sNewPassword
oUser.SetInfo
On Error Goto 0
'--------------------8<----------------------
If there is a chance that the name of the administrator is not
"Administrator" (e.g. the account is renamed, or you have some
non-English OS versions), you could use this version instead:
'--------------------8<----------------------
sNewPassword = "testpassword"
Set oWshNet = CreateObject("WScript.Network")
sComputer = oWshNet.ComputerName
sAdminName = GetAdministratorName
On Error Resume Next
Set oUser = GetObject("WinNT://" & sComputer & "/" & sAdminName & ",user")
oUser.SetPassword sNewPassword
oUser.SetInfo
On Error Goto 0
Function GetAdministratorName()
Dim sUserSID, oWshNetwork, oUserAccount
Set oWshNetwork = CreateObject("WScript.Network")
Set oUserAccounts = GetObject( _
"winmgmts://" & oWshNetwork.ComputerName & "/root/cimv2") _
.ExecQuery("Select Name, SID from Win32_UserAccount" _
& " WHERE Domain = '" & oWshNetwork.ComputerName & "'")
On Error Resume Next
For Each oUserAccount In oUserAccounts
If Left(oUserAccount.SID, 9) = "S-1-5-21-" And _
Right(oUserAccount.SID, 4) = "-500" Then
GetAdministratorName = oUserAccount.Name
Exit For
End if
Next
End Function
