I need to install the DNS service on the secondary domain controller, so that it contains all the same records as the primary. I have done alot of research, and there seems to be many ways of doing it, I am not sure what is best practice and what is safest.
If they were Conditional Forwarders, they have the option to be AD Integrated and automatically appear on all DCs within the replication scope. Here's more info for Windows This posting is provided AS-IS with no warranties or guarantees and confers no rights. This is because AD replication will take care of replicating your zone content to the second DC.
The most important part here would be to update your systems to point to the new DC as secondary DNS system so that, when the first one fails, the second one takes over. Also, do not forget to configure your forwarders as it does not get replicated As Ace already mentioned. Conditional forwarders will be replicated if they are AD-Integrated. To make sure that everything works fine, you can make one of your computers point to the new DNS server and check the internal and external DNS resolution.
Also, use dcdiag to check your DCs health and repadmin to check your AD replication status. This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
Hi Biswajit, I have added the DNS windows component as suggested, all the forward and reverse lookup zones appear automatically within DNS on the new server which I am very pleased about! With its limited functionality, a cache-only DNS server is best suited for a small office environment or a small remote branch office. However, in a large enterprise where Active Directory is typically deployed, more features would be needed from a DNS server, such as the ability to store records for computers, servers and Active Directory.
The DNS server stores those records in a database, or a zone. DNS has a few different types of zones, and each has a different function. We will first create a primary forward lookup zone titled firewall. We do not want to name it firewall.
On the Zone Type screen, make sure that Primary zone is selected and click Next. We now have a foundation that we can place resource records in for name resolution by internal clients. Contrary to the forward lookup zone, a reverse lookup zone is used by the DNS server to resolve IP addresses to host names. Not as frequently used as forward lookup zones, reverse lookup zones are often used by anti-spam systems in countering spam and by monitoring systems when logging events or issues.
To create a reverse lookup zone:. On the Reverse Lookup Zone Name screen, enter There is now a reverse lookup zone titled This will be used to store PTR records for computers and servers in those subnets.
Using the instructions above, go ahead and create two additional reverse lookup zones, one for a There are different types of resource records, and the DNS server will respond with the record that is requested in a query. As such, we will create all but SRV records because Active Directory will create those automatically:. Have the server hit itself for DNS. It will fail to lookup anything other than what you have entered for the local subnet.
Once it fails, it will forward all requests to the router. That's how my home network is setup. Yeah, not the best but is the fastest and lazy way. I am trying to setup DNS on the server, it's on the server, but hasn't been fully configured. If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem.

It may be a good idea to only let LAN users that are part of the domain to query your DNS server to ensure confidentiality of your naming conventions and other sensitive information.
By adding these additional layers to your DNS server you can be assured of. This needs to be opened on the firewall if you need to use your internal DNS for lookups.
Note: this decision will be defined in the planning phase and should be carefully calculated. From a security perspective only publish services to the public domain if it is necessary. If you would like to administer the DNS server remotely you will need to open RCP port only do this is it is necessary and if you have secured the server.
If you are using ISA there are predefined protocol filters that have been define that you can enable. Please make sure that all of the Windows updates are done and the latest drivers and Rom packs have been loaded on the server and applied to the hardware this is essential as you do not want to be applying these changes at a later stage when the machine goes into production. Skipping this step will cause unnecessary down time in future.
Please make sure that the static IP address is assigned to the server before beginning the installation process. After the entire preamble we are now ready to start installing DNS on our newly configured and prepared server. Ensure that you have Windows Server Std is installed and that a static IP address has been assigned. Figure 1. Selecting a DNS server that is consistently up is paramount as external name resolution rests on this resource.
