DHCP Server in DCs and DNS Registrations - StdQry. One common deployment scenario for the DHCP Server service is to have it installed in domain controllers. When this scenario is used it is necessary to define the alternate credentials to be used by DHCP when doing DNS registrations on behalf of the DHCP clients. I wanted to blog about the effects on the registration of the A and PTR records if the DHCP Server is running in a DCs without alternate credentials. The default DHCP configuration is that clients register their A records and the DHCP Server registers the PTR records.
The idea is that the client is the owner of its name, so it is responsible of registering it the DNS namespace, but the owner of the IP is the DHCP server, then it should control its registration in DNS. This default configuration of this option can be seen in the following screenshot: The configuration can be done at the server, scope and reservation level. How to configure DNS dynamic updates in Windows Server 2003. This article describes how to configure the DNS update functionality in Microsoft Windows Server 2003. The DNS update functionality enables DNS client computers to register and to dynamically update their resource records with a DNS server whenever changes occur.
If you use this functionality, you can reduce the requirement for manual administration of zone records, especially for clients that frequently move and use Dynamic Host Configuration Protocol (DHCP) to obtain an IP address. Windows Server 2003 provides support for the dynamic update functionality as described in Request for Comments (RFC) 2136. For DNS servers, the DNS service permits you to enable or to disable the DNS update functionality on a per-zone basis at each server that is configured to load either a standard primary or directory-integrated zone.
Windows Server 2003 DNS update features The DNS service lets client computers dynamically update their resource records in DNS. Notes The interval is set in seconds. Should a domain controller be placed within the DMZ? Generally speaking, it's not a great idea to place domain controllers within the DMZ. As you're probably aware, the primary advantage of a DMZ is that it provides a neutral ground, typically for services that must be accessed by both internal and external users. The compromise of a system within the DMZ will not jeopardize the security of systems located within the secure internal network. Domain controllers, by their nature, are some of the most highly valued assets within the organization. These are the servers that control access to the resources on a Windows network, including the Active Directory database. The most common solution that I've seen out there is to build the DMZ servers as standalone servers. Managing Replication Between Sites.
Although replication within sites is optimized for LAN connectivity and requires little or no management, you have control over when and how replication between sites occurs. You want to maximize efficiency and minimize cost, and there are decisions that must be made on the basis of your network environment, physical location, and business needs. The KCC generates the intersite topology automatically, but the settings on the site links are the factors that the KCC considers in the process. When multiple sites participate in the replication topology of domain controllers in the same forest, the default intersite topology is a least-cost spanning tree, where "cost" is administratively set to favor various routes. Replication between sites can occur synchronously by RPC over IP transport or asynchronously by SMTP over IP transport. Note A spanning tree algorithm is applied to network connections to eliminate redundant routes and thereby reduce consumption of expensive WAN network bandwidth.
Install and Configure DNS on Windows Server 2012. Setting up a Domain Name System (DNS) on Windows Server involves installing the DNS Server Role. This tutorial will walk you through the DNS installation and configuration process in Windows Server 2012. Microsoft Windows Server 2012 is a powerful server operating system capable of many different roles and functions.
