In Windows , the Session Manager Subsystem smss. In the past with Windows or earlier, there was only a single instance of smss. With parallel processing of sessions, technologies like Windows Terminal Services greatly benefit from this enhancement. Rather than having seven Terminal Services clients queued up to log on and run thin client sessions, on an eight-core processor server, each of the seven client sessions can simultaneously log on and run applications at processor speed.

Again, this is a technology that a network administrator does not install, configure, or run separately, but is now built in to Windows , which ultimately improves the raw performance of applications and tasks that used to queue up serially on a server that can now be handled in parallel with each core processor handling the added tasks. This service helps to ensure user sessions are completely terminated when a user logs off of a system. It removes temporary file content, cache memory content, and other information typically generated during a user session, but deemed unnecessary for longer-term storage.

This service is particularly useful for organizations using Windows Terminal Services where user sessions are routinely created on a server, and for security purposes, the user profile data is removed when the user logs off of the session. Hyper-V is a technology built in to the core of the operating system in Windows that greatly enhances the performance and capabilities of server virtualization in a Windows environment.

In the past, virtual server software sat on top of the network operating system and each guest session was dependent on many shared components of the operating system. Hyper-V provides a very thin layer between the hardware abstract layer of the system and the operating system that provides guest sessions in a virtualized environment to communicate directly with the hardware layer of the system. Without having the host operating system in the way, guest sessions can perform significantly faster than in the past, and guest sessions can operate independent of the host operating system in terms of better reliability from eliminating host operating system bottlenecks.

Hyper-V and server virtualization is covered in more detail in Chapter 37, "Deploying and Using Windows Virtualization. As much as there have been significant improvements in Windows under the hood that greatly enhance the performance, reliability, and scalability of Windows in the enterprise, Windows servers have always been exceptional application servers hosting critical business applications for organizations.

Windows continues the tradition of the operating system being an application server with common server roles being included in the operating system. When installing Windows , the Server Manager console provides a list of server roles that can be added to a system, as shown in Figure 1.

This book focuses on the Windows operating system and the planning, migration, security, administration, and support of the operating system. Windows is also the base network operating system on top of which all future Windows Server applications will be built.

Windows Server Datacenter The Datacenter edition is intended only to large enterprise market , the main difference from the Enterprise is on the number of virtual machines that can be used with a single license is unlimited. Normally a license of the Datacenter will be associated with a physical server in the form of OEM, meaning that they can be only been bought together.

The reason is that these servers typically cost tens or even hundreds of thousands of dollars and the support from those who sold is given about the software and hardware, is not permissible for a server to stop due to a faulty motherboard much less by a system error. Windows Server Server Core All editions of Windows Server have two types , Full and Server Core Installation , Full installation is where most functions are managed via the GUI graphical user interface or CLI command line interface , Server Core run only in CLI , and it has two direct implications : First, a reduction in the attack interface, which means that the attacks of malicious agents is decreased.

The second implication is that once running the server will have fewer components requisites for the installation are simpler, as less memory and processing. The most of time, you can use MMC, and add a snap-in for use configure you're Server Core after enabling preferences with sconfig. Reference: Training kit , Microsoft Press.

Stand-alone download managers also are available, including the Microsoft Download Manager. The Microsoft Download Manager solves these potential problems.

It gives you the ability to download multiple files at one time and download large files quickly and reliably. It also allows you to suspend active downloads and resume downloads that have failed.
