At this point, if you click on the Features option, you should see several features installed, including WINS server as shown in Figure 6-11. Figure 6-11 Server 2008 features list 8. To have the WINS server take care of name resolution for Windows clients, go to the IP Properties window of the client computer, then click the Advanced button and click the WINS tab. From there, one or more WINS servers can be added. Table 6-1 Networking services C OMMAND D ESCRIPTION DHCP Short for Dynamic Host Configuration Protocol. It allows prop- erly configured client computers to obtain IP addresses auto- matically from a DHCP server. Terminal Services A type of thin-client terminal server computing. It allows client computers to connect to and take control of a server. Thin-client computers and PCs can connect to servers running Terminal Services. Routing and Remote A network service in Windows Server 2008, Windows Access Service RRAS Server 2003, and Windows Server 2000. It allows an adminis- trator to configure dial-up remote access servers, VPN servers, and configure IP routing, as well as NAT. IPsec A protocol within the TCPIP suite that encrypts and authenti- cates IP packets. It is designed to secure any application traffic because it resides on the network layer. continued 142 | Lesson 6 Table 6-1 continued C OMMAND D ESCRIPTION DNS A worldwide service that resolves host names to IP addresses. This facilitates proper communication between computers. A hierarchy of DNS servers communicates with each other in an effort to teach one another their name resolutions. WINS A service that resolves NetBIOS names to IP addresses. It is Microsoft’s version of the NetBIOS Name Service NBNS combined with a name server.
