For a server to serve other clients, it will need connect to and communicate over the network. Therefore, you need to know how to connect the server and configure the TCP/IP properties and IP Address Settings.

Although servers may use wireless cards to connect to the network, most servers use wired connections to communicate. The cable connections will be faster, more reliable, and more secure. In either case, you need to configure the following on a computer running Windows Server 2008 R2:
• IP address and its corresponding subnet mask (uniquely identifies the computer using a logical address)
• Default gateway (nearest router that connects to the other networks or the Internet)
• One or more DNS servers provide name resolution (domain/host name to IP address).

The IP address, subnet mask, default gateway, and DNS servers can be configured manually or automatically via a DHCP server. Because servers provide services to multiple clients, the network addresses are manually assigned and don’t change much.

CONFIGURE THE IP
To configure the IP in Windows Server 2008 R2, do the following:
1. Open the Control Panel.
2. To access the network connection properties, do one of the following:
• While in Category view, click Network and Internet, then click Network and Sharing
Center, and finally, click Change adapter settings.
• If you are in Icon view, double-click Network and Sharing Center, and then click Change adapter settings.
• Right-click the network icon in the notification area, select Open Network and Sharing Center (Figure 1), and then click Change adapter settings.

3. Right-click the connection that you want to change, and then click Properties.
4. Under the Networking tab, click either Internet Protocol Version 4 (TCP/IPv4) or
Internet Protocol Version 6 (TCP/IPv6), and then click Properties.
To specify IPv4 IP address settings, do one of the following:
• To obtain IP settings automatically from a DHCP server, click Obtain an IP address
automatically, and then click OK.
• To specify an IP address, click Use the following IP address, and then, in the IP address,
Subnet mask, Default gateway, Preferred DNS server, and Alternate DNS server boxes, type the appropriate IP address settings. See Figure 2.

To specify IPv6 IP address settings, do one of the following:
• To obtain IP settings automatically, click Obtain an IPv6 address automatically, and then click OK.
• To specify an IP address, click Use the following IPv6 address, and then, in the IPv6 address, Subnet prefix length, and Default gateway boxes, type the IP address settings. See Figure 3.

Before moving on to the next section, you should understand how proxy settings affect your access to the network or the Internet. A proxy server is a server that is used to translate between public and private networks using Network Address Translation (NAT). It is usually placed on the edge of a corporate network. With NAT, you can have a single public address and multiple private addresses. A proxy server hides the internal addresses and allows you to have a multitude of private addresses.
When you purchase a wireless router for your house, you connect your cable or DSL modem to the wireless router, which will be assigned a public external address. You can then connect multiple computers or hosts inside your house, which are assigned private addresses. The router will then translate between the public address and the private addresses.
Usually when you go to the Internet within a corporation, you need to specify the address and port of the proxy server. If not, while you may be able to access internal resources, you will not be able to access resources on the Internet.
To change the proxy settings for Internet Explorer (which is also used for other applications), you can do one of the following:
• Start Internet Explorer. Then select the Connections tab and click the LAN settings button.
• While in Category view in the Control Panel, click network and Internet, then click Internet Options. Next select the Connections tab and click the LAN settings button.
• While in Icon view, double-click Internet Options. Then select the Connections tab and
click the LAN settings button.
Most corporations should have servers that automatically configure the proxy settings when you have Automatically detect settings enabled. However, if you need to use a different proxy server, you will need to deselect the Automatically detect settings and select the Use a proxy server for your LAN option. You will then specify an address and port number for your proxy server. Common ports are 80, 8080, and 3128. Because you don’t want to go through the proxy server for your internal servers, you should select the Bypass proxy server for local address box. See Figure 4.
