c. Set the DHCP server to provide clients the address to DNS2. d. Set the DHCP server to provide clients the address to ISPDNS2. 3. A user in the branch office reports that he cannot use Internet Explorer to view a commonly used Web site on the Internet. At your client computer in the main office, you run Nslookup to verify the target address and receive the correct address. At the user s client computer, you also run Nslookup, but the address returned is incorrect. What should you do to troubleshoot (Choose all that apply.) a. Verify that the client is using the correct DNS servers. b. Run Ipconfig /flushdns. c. Select the Network Connections icon in Accessories. d. Run Ipconfig /renew.

To troubleshoot connectivity issues, you must determine whether the problems are related to networking or related to name resolution. If the connectivity issue is related to TCP/IP routing, you can use PathPing to determine at which point in the route the packets are stopped. If a problem is related to DNS, you must ensure that the client has the correct DNS server information. If so, first use the Nslookup command to verify that the server is correctly returning what you re expecting. Then verify the DNS server s forwarders.

Diagnosing and Resolving Issues Related to Service Dependency
Your server running Windows Server 2003 is not just a black box that takes in raw data and produces more raw data again. Indeed, a server running Windows Server 2003 (or any other Microsoft server, for that matter) is made up of a collection of processes, which each perform a specific task. Sometimes, these tasks run as services. A service can run either in the foreground requiring user interaction or in the background requiring no interaction. Often, services run in the background and require little to no user interaction to perform the specified job. Depending on which Windows Server 2003 components you choose to load at instal lation, Windows Server 2003 can have upward of 100 services! If you choose to load other Microsoft products or third-party software on your server running Windows Server 2003, it too will likely load additional services. To see the current services installed on a specific server, on the Start menu, right-click My Computer, and select Manage. Then select the Services node in the Computer Man agement console, as shown in Figure 12-24.

Services can be in one of three possible states: started, stopped, or paused. Three pos sible methods exist to configure a service for starting:
Automatic
The service starts automatically when the system is restarted.
Manual The service does not start automatically when the system is restarted; however, if another process calls upon this service to start, the service will start. Disabled The service will not start automatically when the system is restarted; the service will not start even if another process calls upon this service to start.
Some services depend on other services in order to start. It is like an automobile; there is no reason for the engine to turn over if the fuel pump is not working and will not give the engine any gas. Services are the same way: some are layered, and there is no reason to start unless the components underneath aren t already working properly. This idea is called a service dependency. That is, some services depend on other ser vices in order to start. Therefore, if even only one service is not working properly, it could have a cascading effect throughout your entire server. If you take a closer look at the Remote Access Connection Manager by double-clicking it and selecting the Dependencies tab, you can see the services it depends on to start, as well as the services that depend on it to start, as shown in Figure 12-25.
