The configuration of a network connection in Windows Vista, like Windows XP, is something that is usually done by automatically once the system detects the network card.

But sometimes interested in doing a manual configuration of this connection. And this is often for many reasons, one being that we need to connect your computer with the same IP (talking about the private IP, public IP that we have said repeatedly that depends on your ISP server).

Let's see how to manually configure the network connection, and in particular paragraph TCP / IP, which is the user level of interest.

To begin, let's see how to access the network connection.

Let's start and in the right panel we have Red.

A picador network and shows the next window, with our network connections.

At the top we see a link to Center Network and Sharing. we click on this link and we will display the following window:

In this window Center Network and Sharing in the left pane, you have the option Manage network connections.

NOTE: This window Center Network and Sharing can also arrive as follows: Start -> right click on Network -> Properties.

Well, once we click on Manage Network Connections window shows us that we see below:

In this window we see our network connections. Picamos with the right mouse button (usually the right), and in the context menu that we deploy, we Properties to get to the next window.

In this window we see the element which uses that connection. Come directly to Internet Protocol version 4 (TCP/IPv4) and we go to the next window.

In this window we see two tabs. Configuration with one another and with the General Settings option.

On the General tab is where we will configure the properties of our connection.

We are two choices: Obtain an IP address automatically (ticked by default) and Use the following IP address:.

By checking this option will activate the cells of data so we can put our link. These data are:

.- IP address is the IP address to be given to our PC. In a network, this IP address must be provided within the same range. A typical IP address would be 192.168.1.2. IP addresses of other computers on the network should start with 192.168.1.x, where x is the number assigned to each computer. Within a network there can be two computers with the same IP, and if there is more than a conflict occurs, connecting to the network only the first computer that requested it.

.- Subnet mask is the mask that defines our subnet within a larger network. The Subnet Mask must be within a range, depending on the range of IP address. Windows, nibbling on the first set of three digits, calculates and automatically enters the appropriate subnet mask. As with the IP address within this range we can vary the final value, but always remembering that for our machines are, the subnet mask must be the same on all machines.

Default gateway .- This section will the IP address of the gateway (the IP address for access to our router, so there is no misunderstanding). This Gateway Wateway or should be in the same range as the rest of the network, and typically is assigned the first IP address range (in the example that we would be putting 192.168.1.1). Although it may vary if the same has to be configured on the router.

Here is the configuration of the DNS.

The DNS (Domain Name System), which is a hierarchical database that contains data and distribution of domain names. For our purposes, what is configure the IP address of the server through which we will access this database. DNS has many functions, but the principal is converted to the user domain address (eg www, configurarequipos.com) into its corresponding IP address, and that what really connects with an IP address is your page.

We have two options here: Get DNS server address automatically (enabled by default), in which case they are set directly on the Internet connection (in the properties of the WAN router) and use the following DNS server addresses:

Here we show two IP addresses. One of the Preferred DNS server and Alternate DNS server.

These DNS server addresses provided by us our ISP, but no major problems in using other servers. We use two (preferred and alternate) for the case the first is out of service or busy.

To activate the manual configuration of DNS is first necessary to activate manually configuring the IP address, but once we set the DNS to redial Obtain an IP address automatically and keep only the DNS configured manually.

As already mentioned, there is one for the Alternate Configuration tab.

This alternative configuration is used in cases where a computer is connected over a network.


Advanced Settings:

On the General tab there is a button to access the Advanced Settings. As always, keep in mind that a configuration is for advanced users, since their use requires some knowledge about what is being done.

Clicking on this button to access the advanced settings, which are three tabs:

IP Configuration:

It shows whether the DHCP (Dynamic Host Configuration Protocol) is enabled or not. For automatic configuration of IP addresses the service has to be enabled.

Then we have the IP address and Gateway.

The option presented to us under the name Metrics automatically enabled by default, allows us to define the metrics by hand (this reserved for users who know very well what they are doing, so it should be left as is.

Automatic Metric specifies whether TCP / IP automatically calculate a value for a metric-based interface in the speed of the interface. The interface has the higher speed interface metric value lower.

Metric of the interface provides a location to enter a value for the metric of this interface network connection. A low value for the metric interface indicates a higher priority for using this interface.

DNS:

In this tab we see the IP addresses of DNS servers. You can add more addresses of DNS besides the two that gives us our ISP, which sometimes we could ensure a connection in the event of a fall of DNS servers of our ISP.

WINS:

‘WINS (Windows Internet Naming Service) is a Microsoft server for NetBIOS names, which maintains a table of correspondence between IP addresses and NetBIOS names for computers to quickly locate another computer on the network.

WINS is not used practically, as it has been replaced by the DNS servers, but to establish a network with computers with Windows versions prior to 2000 it is necessary.

Inside we see the WINS Enable NetBIOS over TCP / IP. This option is necessary to take on for our team is available to Mac or Linux networks.

To manually configure this tab you need to be working with IP's configured manually (except for Enable NetBIOS over TCP / IP and above). Touching these options should only be done if we know for certain what we are doing.

In these we see tabs at the top right a question mark (?). This is a quick access to assistance. Just biting on it (which will change the mouse pointer) and then on the word or action on which we receive information.

It is highly recommended to use this Help system before touching any parameter of this configuration of the network connection.
