Description:This is a good book if you want to understand more about Cisco's technology or models would be best for your network when you are going to implement Windows 2000 and Active Directory. The main problem that I have is that in all chapters the author tends to say the exact same thing over and over again. Also, they have a lack of understanding of certain roles within Active Directory. For instance, they say that you can have only one Global Catalog per domain. This is incorrect. You can have as many GC's as you want within your domain. They say that the PDC FSMO role will authenticate logon traffic. This is true, but the GC plays a major role in this. The PDC Emulator FSMO DC will query the GC for the account and SID. Then the user will be logged in.Also, in the second to the last chapter, they say that you cannot use SYSPREP to prepare a Windows 2000 server (Server or Advanced Server) for duplication. This is not true, unless you have installed Active Directory on the server. Then, you can run SYSPREP, but you will not be able to remove AD or rename the server.There are some mistakes in this book, but if you want to know the Cisco technology, they do explain it in good detail.If you are a seasoned pro, then do not get this book. Pick up the Windows 2000 Server Resource Kit, if you haven't done so already.
