如何传递凭据来重命名命令？

我在 PowerShell 脚本中运行以下命令来简单地重命名计算机。该脚本将由计算机启动脚本 GPO 执行，因此我需要在命令中传递凭据。由于我无法看到脚本在启动时执行时发生了什么，因此我通过以普通用户身份登录时运行脚本来测试它

(Get-WmiObject win32_computersystem).Rename( $NewName,'Password','domain\username')

该命令返回 ReturnValue '5' - 访问被拒绝。我如何传递用户名和密码？ （我了解脚本中密码的安全风险）

__GENUS          : 2
__CLASS          : __PARAMETERS
__SUPERCLASS     : 
__DYNASTY        : __PARAMETERS
__RELPATH        : 
__PROPERTY_COUNT : 1
__DERIVATION     : {}
__SERVER         : 
__NAMESPACE      : 
__PATH           : 
ReturnValue      : 5
PSComputerName   : 

如果您总是在同一台计算机上运行它或者关联的帐户漫游，那么 IIRC 您可以依靠 DPAPI 来存储密钥，如下所示：

# Capture once and store to file
$passwd = Read-Host "Enter password" -AsSecureString
$encpwd = ConvertFrom-SecureString $passwd
$encpwd
$encpwd > $path\password.bin

# Later pull this in and restore to a secure string
$encpwd = Get-Content $path\password.bin
$passwd = ConvertTo-SecureString $encpwd

# Extract a plain text password from secure string
$bstr = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($passwd)
$str =  [System.Runtime.InteropServices.Marshal]::PtrToStringBSTR($bstr)
[System.Runtime.InteropServices.Marshal]::ZeroFreeBSTR($bstr)
$str

如果这不起作用，您可以使用此方法，但它不如上述方法安全：

$key = 1..32 | ForEach-Object { Get-Random -Maximum 256 }
$passwd = Read-Host "Enter password" -AsSecureString
$encpwd = ConvertFrom-SecureString $passwd -Key $key
$encpwd

# Could easily modify this to store username also
$record = new-object psobject -Property @{Key = $key; EncryptedPassword = $encpwd}
$record
$record | Export-Clixml $path\portablePassword.bin

# Later pull this in and restore to a secure string
$record = Import-Clixml $path\portablePassword.bin
$passwd = ConvertTo-SecureString $record.EncryptedPassword -Key $record.Key

# Extract a plain text password from secure string
$bstr = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($passwd)
$str =  [System.Runtime.InteropServices.Marshal]::PtrToStringBSTR($bstr)
[System.Runtime.InteropServices.Marshal]::ZeroFreeBSTR($bstr)
$str
