检索DHCP Scopes

Question

我的脚本在本地运行时工作，我试图从远程服务器获取所有DHCP作用域信息，我收到脚本下面的错误。

$A = "TestDH01"
ForEach ($B in $A) {

Get-DHCPServerv4Lease -ScopeID $_.ScopeID -AllLeases | where 
{$_.AddressState -like '*Reservation'}

} Select-Object ScopeId,IPAddress,HostName,ClientID,AddressState | ExportCsv "\\TermServer\d$\New\Steve\$($A)-Reservations1.csv" -NoTypeInformation

Get-DhcpServerv4Leases:无法验证参数'ScopeId‘上的参数。参数为空或空。提供一个非空或空的参数，然后再试一次该命令。在行:4字符:36+Get-DHCPServerv4租赁-ScopeID $.ScopeID -AllLeases x，其中{$。.+ ~~ + CategoryInfo : InvalidData：(:) Get-DhcpServerv4租赁，ParameterBindingValidationException + FullyQualifiedErrorId : ParameterArgumentValidationError，Get-DhcpServerv4租赁

Answer 1

我猜你是在找这样的东西：

#Get all DHCP Servers
$ServerList = Get-DhcpServerInDC | select IPADdress, DNSName
foreach ($server in $serverlist)
{
#Get the scopes from each server
    Get-DHCPServerv4Scope -ComputerName $server.IPAddress | select ScopeID | 
#Get the lease information for each scope
    ForEach-Object {Get-DHCPServerv4Lease -ScopeId $_.ScopeId -ComputerName $Server.DNSName -AllLeases  | 
        where {$_.AddressState -like "*Reservation"} | Select-Object ScopeId,IPAddress,HostName,ClientID,AddressState }
}
