Administrators should disable this as needed. The multiple assignment of IP addresses to an interface should only be the exception. This makes the error search unnecessarily difficult.

Hey you! Yes, you! Configuring Multiple Network Adapters or Media Types Windows XP Professional places no restrictions on physically multihomed computers, so you can add as many network adapters as the computer hardware can accommodate, and assign each a separate address.
The device driver for each adapter is installed and any internal resources are automatically configured. If the network adapter is not Plug and Play compliant, the adapter software must be installed and configured manually using the manufacturer s instructions. For a multihomed computer that uses multiple network adapters for physical connections to the LAN, each adapter appears as a separate adapter in the Network Connections folder.
For a system configured to support multiple network or media types, there are no restrictions for this type of configuration other than hardware and media support. WAN, using circuit-switched media such as ISDN and dial-up, dedicated asynchronous lines, dedicated synchronous lines such as T-Carrier, and virtual-circuit wide-area media such as X.
In Network Connections, right-click the local area network connection you want to modify, and then select Properties. For more information about how to configure a multihomed system using a single network adapter, see Configuring IP Addressing and Name Resolution in this book.
It is possible to change this default setting by entering the DNS suffix for a particular connection in the appropriate text box. In Network Connections, right-click the local area connection you want to modify, and then click Properties. In the Internet Protocol Properties dialog box, click Advanced. The settings on the WINS configuration tab are used only for the adapter you are configuring. While it is possible to configure a default gateway IP address for each network interface, there is only a single active default route in the IP routing table.
Although teaming sounds like a good idea to eliminate a multihomed scenario for such cases where both NICs are on the same segment and you have the NIC vendor software installed that offers teaming, but I must point out that teaming NICs on DCs, or any other servers , is not recommended, nor is it supported by Microsoft:. Teamed network cards for domain controllers? Disable the ability for the outer NIC to register.
The following link will show you how:. First, get the list of interfaces: wmic nicconfig get caption,index,TcpipNetbiosOptions. More info on the wmic commands and the registry entries can be found in this forum thread link:.
A multihomed machine will cause duplicate name errors on itself because Windows sees itself with the same name in the Browse List My Network Places , but with different IPs. You can only have one, hence the error generated. That is done in NIC properties by unchecking the respective service under the general properties page.
If you need these services on the outside NIC which is unlikely , which allow other machines to connect to your machine for accessing resource on your machine shared folders, printers, etc. To the right, you will see the IP address referencing the GC address. That is called the GcIpAddress. To stop these two records from registering that information, use the steps provided in the links below:.
The one section of the article that disables these records is done with this registry entry:. For a system configured to support multiple network or media types, there are no restrictions for this type of configuration other than hardware and media support.

While it is possible to configure a default gateway IP address for each network interface, there is only a single active default route in the IP routing table. This behavior often lead to confusion and loss of connectivity. Windows XP Professional now provides the network administrator or a user who has appropriate permissions with two options.
One enables the automatic determination of a routing metric based on the speed of the interface. The metric indicates the cost of the route.
