Example & Expl. If your DNS server is running Windows Server Core, you can configure conditional forwarders on your DNS server from the command-line by using the DNSCMD command. A conditional forwarder is a forwarder that handles queries only for a specified domain name. Conditional forwarding enables a DNS server to forward queries for different domain names to different DNS servers according to the specific domain names that are contained in the queries. This improves conventional forwarding by adding a second condition to the forwarding process. To configure a conditional forwarder, you specify a domain and one or more IP addresses of DNS servers that can resolve queries directed to that domain. You can use Dnscmd to configure conditional forwarders for your DNS server. For example, to configure a conditional forwarder that forwards all queries for hosts in the microsoft.com domain to the external DNS server 207.68.160.190, do the following: dnscmd SEA-SC4 /zoneadd microsoft.com /forwarder 207.68.160.190 If your DNS server is on a domain controller, use /dsforwarder instead of /forwarder in this command.

If your DNS server is running Windows Server Core, you can configure forwarders on your DNS server from the command-line by using the DNSCMD command. A forwarder is a special DNS server that you designate for handling client requests that your regular DNS servers cannot or should not resolve, such as requests for offsite or external DNS domain names. DNS clients typically make recursive queries, which are queries to which the responding DNS server must return a valid (success or failure) response. When the DNS server receives a client request and if a forwarder is configured on the DNS server, the DNS server sends a recursive query to the forwarder asking for a valid response. You can use the Dnscmd command to configure one or more forwarders on a Server Core DNS server. For example, to configure the external DNS server 192.0.2.25 as a forwarder for DNS server SEA-SC4, do the following: dnscmd SEA-SC4 /ResetForwarders 192.0.2.25 /timeout 5 /slave
