浅谈Windows ServerDNS 条件转发命令

#备份操作

#创建备份目录
md d:\dns
#筛选需要备份的条件转发，并导出
Get-DnsServerZone|?{$_.ZoneType -like "Forwarder"}|?{$_.ZoneName -like "*corp.com"}|Select-Object ZoneName,@{Name = 'MasterServers';Expression = {$_.MasterServers -join ","}},UseRecursion,ForwarderTimeout|Export-Csv -Path D:\dns\Forwarder.csv -NoTypeInformation -Encoding UTF8

#删除操作

Get-DnsServerZone|?{$_.ZoneType -like "Forwarder"}|?{$_.ZoneName -like "*corp.com"}|Remove-DnsServerZone -Force

#恢复操作

#导入备份的内容
$dns=Import-Csv D:\dns\Forwarder.csv -Encoding Default
#循环添加条件转发器（-UseRecursion 是开启递归查询）
foreach($info in $dns){
Add-DnsServerConditionalForwarderZone -Name $info.ZoneName  -MasterServers $($info.MasterServers.Split(",").foreach{[System.Net.IPAddress]$_}) -ForwarderTimeout $info.ForwarderTimeout -UseRecursion
}
