我有一个powershell脚本，它以提升的域管理员身份调用另一个脚本，该脚本返回一个访问被拒绝的错误，如下所示：

Exception calling "Add" with "1" argument(s): "Access is denied.
"
At \\server\software$\!SystemSetup\PS_Scripts\LocalAdmin.ps1:16 char:5
+     $AdminGroup.Add($User.Path)
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : CatchFromBaseAdapterMethodInvokeTI

使用此方法调用脚本会产生错误：

$Cred = Get-Credential

Start-Process -FilePath "powershell.exe" -ArgumentList "-NoProfile -NoExit -ExecutionPolicy Bypass -File $ScriptLocation" -Credential $Cred

但是，如果我只需右键单击并以管理员身份运行，然后输入我的域凭据来调用脚本(不使用$Cred)，就可以正常工作：

Start-Process -FilePath "powershell.exe" -ArgumentList "-NoProfile -NoExit -ExecutionPolicy Bypass -File $ScriptLocation"

我调用的脚本如下所示：

$WindowsVersion = Get-WmiObject -Class Win32_OperatingSystem | ForEach-Object -MemberName Caption

If ($WindowsVersion -match 'Microsoft Windows 10 Enterprise') {

    $DomainName = "DOMAIN.COM"
    $ComputerName = (hostname)
    $Username = (Get-CimInstance -ClassName Win32_ComputerSystem | Select-Object -ExpandProperty UserName).Split('\')[1]
    $AdminGroup = [ADSI]"WinNT://$ComputerName/Administrators,group"
    $User = [ADSI]"WinNT://$DomainName/$UserName,user"
    $AdminGroup.Add($User.Path)

    Write-Host "$Username added to Administrators" 

} Elseif ($WindowsVersion -match 'Microsoft Windows 7 Enterprise' -or $WindowsVersion -match 'Microsoft Windows 7 Professional') {

    $DomainName = "DOMAIN.COM"
    $ComputerName = (hostname)
    $Username = (Get-WmiObject -Class Win32_ComputerSystem | Select-Object -ExpandProperty UserName).Split('\')[1]
    $AdminGroup = [ADSI]"WinNT://$ComputerName/Administrators,group"
    $User = [ADSI]"WinNT://$DomainName/$UserName,user"
    $AdminGroup.Add($User.Path)

    Write-Host "$Username added to Administrators" 

} Else {

    Write-Host "Could not determine OS version"
}

我不明白为什么一旦访问到$AdminGroup.Add($User.Path)，在$Cred中存储我的域管理员凭据并将其传递给脚本会导致访问被拒绝

根据TheIncorrigible1的注释，您可以在脚本的开头添加以下内容，以检查它是否以管理员身份运行。如果不是，它将以admin身份重新启动

If (-Not ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) {
    $Arguments = "& '" + $MyInvocation.MyCommand.Definition + "'"
    Start-Process Powershell -Verb RunAs -ArgumentList $Arguments
    Break
}
