Analysis of WindowsServer2008 application

It has been more than a year since using Microsoft's latest server operating system, Windows Server 2008. During the use, I also experienced many advantages and advantages of Windows Server 2008. Today, I will use the MCT platform to write some places and feelings that I need to pay attention to during the process of using them. If you have any mistakes, please ask the same people to enlighten me.

First, the emergence of Server Core features is an innovation. In the past, Unix administrators who used to be a low-energy, virtualized, graphics-free, server-only server system that plays the role of DHCP and DNS servers in a protected environment feel great, but now Windows Server 2008 can do the same. The Core installation mode in Windows Server 2008, after the Server Core mode is installed, the interface is no longer a Windows interface, but a command line interface. All operations are done with commands and scripts, and it feels back to the DOS era. 1. Common configuration commands: 1) Use Ctrl+Shift+Esc to call the task manager, then use CMD to call up the command line window. All the things are done with this window. 2) Change the user password with this net user username password 3 Change the system time and locale with: Control timedate.cpl Control intl.cpl This is just two console commands that are reserved. 4) IP configuration common commands: First check the interface with the command netsh interface ipv4 show interfaces, you will see two interfaces, the Idx of Local Area Connection is 2 and then use the command netsh interface ipv4 set address name=”2” source=static address =IP address mask= subnet mask gateway=gateway netsh interface ipv4 add dnsserver name=”2” address=DNS server 1 address index=1 --add the first DNS netsh interface ipv4 add dnsserver name=”2” Address=DNS server 2 address index=2 --Add the second DNS Check with ipconfig /all 5) Change the computer name: Use the command netdom renamecomputer %computername% /newname: new name System prompt confirmation, press Y and then use the command shutdown /r /t 0 Restart the system and check the new name with hostname. 6) Enable automatic update: c:\\windows\\system32>cscript scregedit.wsf /? View command parameters c:\\windows\\system32>cscript scregedit /AU /v View Currently update service status automatically, 4 is enabled, 0 is disabled c:\\windows\\system32>cscript scre Gedit /AU 4 Turn on automatic update 7) Similarly, enable remote desktop: c:\\windows\\system32>cscript scregedit /AR 0 8) Activate the server c:\\windows\\system32>cscript slmgr.vbs –xpr display expiration time c :\\windows\\system32>cscript slmgr.vbs –dli Display license information c:\\windows\\system32>cscript slmgr.vbs –ato Activate the server 9) Install the server component: Check the currently installed components with the command: oclist to see the default No components are installed, from here you can remember the name of the component to be installed and then use this command to install: start /w ocsetup component name For example, install DNS: start /w ocsetup DNS-Server-Core-Role must pay attention to capitalization when writing !

2. Modify the desktop resolution

In Windows Server 2008 Core, the desktop resolution cannot directly modify the desktop resolution with the graphical interface. You need to modify the registry. After entering the registry, the desktop resolution key value is located at: KLM\\System\\CurrentControlSet\\Control\\video. There may be multiple folders named with GUID in this directory. You need to know the GUID of the graphics card currently used by your system. Use this command to know the graphics driver used by your current system: sc query type= driver group= video . There are two points to note here: 1) There is no space between type and =, there is a space between = and driver; likewise, there is no space between group and =, between = and video There are spaces, there can be no errors, otherwise the command fails to run! Remember the resulting graphics card name, then look at the Device description in the 0000 subdirectory of the above registry directory, find the graphics card you are using now, and then modify the two key values ​​DefaultSettings.XResolution and DefaultSettings.YResolution. 2) This is hexadecimal data, so 1024×768 should be filled in 400 and 300,800× 600 should be filled with 320 and 258 respectively. After doing this, restart the system with the command shutdown -r -t 0.

3. Windows Server 2008 does not require very high hardware configuration.

Of course, PowerShell's shell can also run on Server Core. In this tool, users can configure their own servers or write their own scripts. With the Server Core model, many enterprise servers can be smoothly upgraded to Windows Server 2008 without upgrading the hardware, which protects the company's investment and reduces the company's investment in the network. In Server Core mode, the system runs faster, after all, only the necessary components are installed, and the running speed is guaranteed. Depending on your needs, you can even install Windows Server 2008 on very old devices without the need to upgrade your hardware. In addition, the administrator can also remotely manage the Server Core installation without a graphical interface, just open the TCP3389 port.

Second, about Hyper-V

Windows Server 2008 has many exciting and innovative features in virtualization technology and management solutions: Windows Server 2008 can be built-in server virtualization technology. Helping companies reduce costs, improve hardware utilization, optimize infrastructure, and increase server availability; although Microsoft has streamlined its virtualization software, "Viridian", it does not live up to the company's expectations and can effectively reduce overall costs. Although VMware is unique in the virtual machine space, Viridian has enabled both Intel and AMD to provide support for hardware-based virtualization, providing a virtual hardware support platform that VMware can't do. According to relevant statistics, US companies have already spent billions of dollars on processor resources that they simply cannot use, but this is not their fault, but the operating system management problem causes up to 85% of CPU resources to be idle. . A major goal of Windows Server 2008 plus virtualization is to enhance idle resource utilization and reduce waste.

Although Hyper-V is very good quality, it also has a fatal flaw: unlike Virtual PC, except for the small changes in the graphical management interface, Hyper-V does not have any VMs introduced from the product. Features, and even these introductions are not workspace-independent; another very strange aspect of Hyper-V is the lack of a physical-to-virtual conversion utility that can't be dragged directly from a physical desktop to a virtual desktop like Virtual PC. When a virtual network switch is established, the front of the IPv4 protocol on the original physical network card is removed, and a new virtual network card is generated for the Parent OS. However, when the RC0 is used, the virtual network card has no IP address, RC1. Will set the static IP address on the original physical network card. Hyper-V is a great system, but it's best to do a good job before you decide to use it.

Third, greater control and enhanced protection

With Windows Server 2008, IT professionals have more control over the server and network infrastructure so they can focus on the key Business needs. Enhanced scripting capabilities and task automation capabilities (for example, Windows PowerShell) help IT professionals automate common IT tasks. Role-based installation and management through Server Manager simplifies the task of managing and protecting multiple server roles across the enterprise. The server's configuration and system information is managed from the centralized location of the new Server Manager console. IT staff can install only the roles and functions they need, and the wizard automates many time-consuming system deployment tasks. Enhanced system management tools (for example, performance and reliability monitors) provide information about the system and warn IT staff before potential problems occur. Windows Server 2008 allows administrators to modify their infrastructure to adapt to changing business needs while maintaining the flexibility of this operation. It allows users to execute programs from remote locations such as remote applications and Terminal Services Gateways, a technology that gives mobile workers greater flexibility. Windows Server 2008 uses Windows Deployment Services (WDS) to accelerate the deployment and maintenance of IT systems, using Windows Server Virtualization (WSv) to help consolidate servers. For organizations that need to use domain controllers in their branch offices, Windows Server 2008 provides a new configuration option: a read-only domain controller (RODC) that prevents user accounts from being exposed when security issues occur with domain controllers.

Security is an eternal topic in enterprise network applications. For this reason, enterprises have higher requirements for the security performance of operating systems. Windows Firewall with Advanced Security in Windows Server 2008 is a host-based firewall that protects against malicious users and network programs at runtime. With the Windows Firewall component, you can comprehensively detect incoming and outgoing traffic, changing the drawbacks of existing firewall software to detect incoming traffic. In addition to comprehensive security detection of traffic, the Windows Firewall component also configures new snap-ins for local and remote firewalls. More importantly, administrators can use the commands in the netsh advfirewall environment to perform command line configuration of new Windows Firewall advanced settings. Windows Server 2008 provides this series of new and improved security technologies, enhances the protection of the operating system, and lays a solid foundation for the operation and development of the enterprise. Windows Server 2008 provides security innovations that reduce the kernel's attack surface, making the server environment more secure and stable.

Microsoft Windows Server 2008 represents the next generation of Windows Server. With Windows Server 2008, IT professionals have greater control over their servers and network infrastructure, allowing them to focus on key business needs. Windows Server 2008 improves security by enhancing the operating system and protecting the network environment. Windows Server 2008 also provides IT professionals with the flexibility to accelerate the deployment and maintenance of IT systems, simplify the consolidation and virtualization of servers and applications, and provide intuitive management tools. Windows Server 2008 provides the best foundation for any organization's server and network infrastructure.
