このトピックでは、別のドメインにある Active Directory リソース用の Google Cloud 承認済みネットワークからのクエリが成功するように DNS 転送を構成する方法について説明します。
コンテキスト
マネージド Microsoft AD に参加した Google Cloud VM ドメインを使用する場合、同じ VPC ネットワーク上にないユーザーやオブジェクトを検索しようとすると、その検索は失敗します。デフォルトの Windows 構成ではマネージド Microsoft AD ドメインにクエリが転送されないため、失敗します。代わりに、VM が配置されている VPC の DNS サーバーが使用されます。この DNS サーバーに VPC ネットワークの外部にあるマネージド Microsoft AD のユーザーとオブジェクトに関する情報がないため、ルックアップは失敗します。
DNS 転送は、VPC ネットワークの外部にあるリソースを Google Cloud から解決する必要がある場合に役立ちます。たとえば、マネージド Microsoft AD ドメインがターゲット ドメインと信頼関係がある場合、この構成が必要になります。
始める前に
始める前に、次の構成を確認してください。
Google Cloud VM は Managed Microsoft AD ドメインにドメイン参加している必要があります。

It fails because the default Windows configuration\ndoes not forward the query to the Managed Microsoft AD domain. Instead, it\nuses the DNS server for the VPC where the VM is located. This DNS server does\nnot have information about Managed Microsoft AD users and objects outside the\nVPC network, so the lookup fails.\n\nDNS forwarding is useful in any case where you need to resolve\nresources located outside the VPC network from Google Cloud. For\nexample, if the Managed Microsoft AD domain has a trust relationship with the\ntarget domain, this configuration is required.\n\nBefore you begin\n----------------\n\nBefore you begin, verify the following configurations.\n\n- The Google Cloud VM must be domain-joined to the\n Managed Microsoft AD domain.\n\n- The forwarding target name server is reachable from within your VPC network.\n You can test that it is reachable with the following steps:\n\n ### Console\n\n Before you begin, verify that the\n [Network Management API](https://console.cloud.google.com/marketplace/product/google/networkmanagement.googleapis.com)\n is enabled.\n 1. Go to the\n [**Connectivity Tests**](https://console.cloud.google.com/net-intelligence/connectivity/tests)\n page in the Google Cloud console.\n\n\n [Go to the Connectivity Tests page](https://console.cloud.google.com/net-intelligence/connectivity/tests)\n\n 2. Create and run a Connectivity Test with the following values:\n\n - **Protocol**: TCP\n - **Source**: IP address from your Google Cloud VPC\n - **Destination**: IP address of your on-premises DNS server\n - **Destination port**: 53\n\n Learn more about creating and running\n [Network Connectivity Tests](/network-intelligence-center/docs/connectivity-tests/how-to/running-connectivity-tests).\n\n ### PowerShell\n\n In Windows PowerShell, run the following command: \n\n ```\n nslookup domain-name dns-server-ip\n ```\n\n Learn more about\n [`nslookup`](https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/nslookup).\n\nIf your target is an on-premises domain, verify the following firewall\nconfiguration.\n\n- The firewall must be configured to allow users from the Managed Microsoft AD domain to access on-premises resources. Learn about [firewall configurations for accessing on-premises resources](/managed-microsoft-ad/docs/firewalls#accessing_on-premises_active_directory_resources_from).\n\nIf you are using private DNS forwarding, there are a few additional\nprerequisites.\n\n- Your on-premises firewall must pass queries from Cloud DNS. To allow\n this, configure the firewall to allow Cloud DNS queries from the\n 35.199.192.0/19 IP address range on UDP port 53 or TCP port 53. If you are\n using multiple Cloud Interconnect connections or VPN tunnels, be sure\n that the firewall allows traffic for all of them.\n\n- Your on-premises network must have a route that directs traffic destined to\n 35.199.192.0/19 back to your VPC network.\n\nTarget domain is not on a VPC network\n-------------------------------------\n\nTo configure DNS forwarding from Google Cloud to an on-premises domain\nthat is not on a VPC network, you should use a forwarding zone. Learn about\n[DNS forwarding zones](/dns/docs/zones/zones-overview#forwarding_zones).\n\nTo create a forwarding zone that resolves the on-premises DNS name to the IP\naddresses of on-premises DNS servers, complete the following steps. \n\n### Console\n\n1. Go to the\n [**Cloud DNS**](https://console.cloud.google.com/networking/dns/zones/) page in the\n Google Cloud console.\n\n\n [Go to the Cloud DNS page](https://console.cloud.google.com/networking/dns/zones/)\n\n2. Create a DNS zone with the following values:\n\n - **Zone type** : **Private**\n - **DNS name**: Target DNS name\n - **Options** : **Forward queries to another server**\n - **Destination DNS servers**: IP addresses of target DNS servers\n\nLearn more about\n[creating DNS forwarding zones](/dns/zones#creating-forwarding-zones).\n\n### gcloud\n\nTo create a new managed private forwarding zone, you should use the\n[dns managed-zones create](/sdk/gcloud/reference/dns/managed-zones/create)\ncommand: \n\n```\ngcloud dns managed-zones create name \\\n --description=description \\\n --dns-name=on-premises-dns-name \\\n --forwarding-targets=on-premises-dns-ip-addresses \\\n --visibility=private\n```\n\nLearn more about\n[creating DNS forwarding zones](/dns/zones#creating-forwarding-zones).\n\nTarget domain is on a VPC network\n---------------------------------\n\nTo configure DNS forwarding from Google Cloud to a self-managed domain\nthat is on a VPC network,\n[follow the steps for Cloud DNS](/dns/docs/zones/zones-overview#forwarding_zones)\nthat are relevant for your configuration."]]
