In this lab you’ll plan the Active Directory physical structure for Northwind Traders. You’ll be concerned mainly with Active Directory’s implementation as it relates the company’s Web site and perimeter network. The exercises in this lab coincide with the steps described in Lesson 2, which include defining a site structure, defining an intersite replication strategy, and determining the placement of domain controllers, global catalog servers, and operations masters.
Before you begin this lab, you must be able to
Northwind Traders is implementing a Windows 2000 network that will host a Web site that will be available to external clients through the Internet. Admin-istrators have designed a network topology that includes a perimeter net- work to support the Web services. The network uses one namespace (northwindtraders.com) for internal and external users. The network is confined to one physical location that’s a well-connected LAN set up as a single domain. All connections are fast and reliable.
The perimeter network contains a front-end tier that supports a Web cluster and a back-end tier that supports a Data cluster. The perimeter network is separated from the private corporate network by a firewall. Figure 8.7 shows the network topology of the perimeter network.
As one of the administrators, you’re responsible for planning the Active Directory physical structure for your network. You must design a site structure, prepare a replication strategy, and decide on the placement of domain controllers, global catalogs, and operations masters.
Figure 8.7 - Network topology for Northwind Traders
In this exercise you must determine how you should set up Active Directory sites for the Northwind Traders network. Remember that in defining a site structure you’re working with your network’s physical topology and creating a more general topology that’s based on available bandwidth, network reliability, and network segmentation. As you plan site structure, refer to Figure 8.7.
In this exercise you must determine where you’ll locate the domain controllers. You should base your decisions on the site structure that you created in Exer- cise 1. One of your goals in determining where to place domain controllers is to ensure that client requests for authentication within the perimeter network don’t pass through the firewall into the corporate private network, even in the event of domain controller failure. In addition, client requests generated within the corporate network shouldn’t have to pass through the firewall into the perimeter network for authentication, even in the event of domain controller failure.
In this exercise you’ll determine how to set up Active Directory intersite replication for the Northwind Traders network. Remember that planning for intersite replication consists primarily of deciding how site links will be configured. Of course, replication is facilitated by your site structure, which you determined in Exercise 1. You’ll now take that structure and plan how you’ll configure the necessary site links.
In this exercise you’ll determine where you should place global catalog servers and operations masters. You’ll base your decision on the site structure and domain placement that you determined in the previous exercises. You believe that, given the size of your network, four domain controllers are enough to handle the network load and provide fault tolerance. You’d prefer not to add any equipment at this time.
