DM/Manager is a tool you use now to plan for, and later to help migrate to Windows 2000 This high-level tool allows you to consolidate domains and make them flat a more suitable structure for Windows 2000 migration DM/Manager shows you your current domain structure in the upper pane and the proposed domain structure in the lower pane (see Figure 12-18) Making conversions is as simple as selecting a domain and indicating its position in the post-migration structure Making these changes is as simple as clicking and dragging a domain to its future position This very powerful tool also has an Undo Migration option that allows you to back out of erroneous changes

NICs solely in the Data Link layer is the obvious other duty of the NIC putting the ones and zeroes on the network cable How much more physical can you get Many teachers will finesse this issue by defining the Physical layer in its logical sense that it defines the rules for the ones and zeroes and then ignore the fact that the data sent on the cable has to come from something The first question when you hear a statement like that at least to me is, What component does the sending It s the NIC of course, the only device capable of sending and receiving the physical signal Network cards, therefore, operate at both Layer 2 and Layer 1 of the OSI seven-layer model If cornered to answer one or the other, however, go with the more common answer, Layer 2

More information about any of the DM/Suite applications can be found on FastLane's Web site at wwwfastlanetechcom They are individually priced on a per-managed-user basis DM/Administrator goes for $7 per user; DM/Reporterm, $6 per user; and DM/Manager, $12 per user; or you can get all three for $25 per user Of course, you can negotiate a site license for larger installations

Getting data from one system to another in a simple network (defined as one in which all the computers connect to one hub) takes relatively little effort on the part of the NICs But one problem with simple networks is that computers need to broadcast to get MAC addresses It works for small networks, but what happens when the network gets big, like the size of the entire Internet Can you imagine millions of computers all broadcasting No data could get through When networks get large, you can t use the MAC addresses anymore Large networks need a logical addressing method that no longer cares about the hardware and enables us to break up the entire large network into smaller networks called subnets Figure 2-26 shows two ways to set up a network On the left, all the computers connect to a single hub On the right, however, the LAN is separated into two five-computer subnets

Windows 2000 has much to offer an organization whose business needs can be better met by Windows 2000 technological advancements Your organization will need an initial survey to determine if the benefits outweigh the effort that is required to implement Windows 2000 Once the decision is made to upgrade, a certain amount of planning must be conducted before even a single system is upgraded This planning applies to domain architecture, naming schemes, and administrative boundaries Once the plan is in place, an upgrade strategy can be created and deployed starting with the highest level systems in the network: the primary domain controllers Third-party tools can assist in the migration effort You can even use them to start preparing today for a Windows 2000 environment, by implementing some of the Windows 2000 features into Windows NT systems For example, you can begin now to build virtual domains and virtual organizational units This chapter concludes Part 3 Next, we are going to look at some strategies for building and managing network connections to the Internet, other corporations, and users
