如何在Powershell中跨多个作用域查询Windows DHCP服务器的主机名

$dhcpServers = Get-DhcpServerInDC

foreach ($server in $dhcpServers) {
    $serverName = $server.DhcpServerName
    $dcName = $server.DomainControllerName

    Write-Host "Querying DHCP server $serverName on domain controller $dcName"

    $scopes = Invoke-Command -ComputerName $serverName -ScriptBlock {
        Get-DhcpServerv4Scope
    }

    foreach ($scope in $scopes) {
        $scopeId = $scope.ScopeId

        Write-Host "Querying scope $scopeId"

        $leases = Invoke-Command -ComputerName $serverName -ScriptBlock {
            param($scopeId)
            Get-DhcpServerv4Lease -ScopeId $scopeId
        } -ArgumentList $scopeId

        foreach ($lease in $leases) {
            $hostname = Invoke-Command -ComputerName $serverName -ScriptBlock {
                param($lease)
                Get-DhcpServerv4OptionValue -ScopeId $lease.ScopeId -IPAddress $lease.IPAddress -OptionId 12
            } -ArgumentList $lease

            Write-Host "IP: $($lease.IPAddress), Hostname: $($hostname.Value)"
        }
    }
}
