Pay attention to the partition. 2. if the system is reinstalled, in order to prevent partition table errors, the C disk is generally not deleted, but the new system is basically installed directly in the original system of the C disk, the C disk is automatically formatted during installation; 2. after installation, you must first install the NIC Driver and configure IP addresses and DNS connections. enable "Remote Desktop" in the "my computer" attribute. If "Windows Firewall" is enabled, select "Remote Desktop" in the exception section. 4. generally ** install the Operating System

2. Enter "ipconfig" or "ipconfig/all" in the command line to view network configuration information such as MAC and IP addresses;
3. View CPU, memory, and other information in the "my computer" attribute. As for the hard disk information, open "my computer" and you will know it.
--------------------------------

** Test network connectivity

1. In the "run" window, enter the "cmd" command and press enter to open the "command line program" window;
2. Enter "ping + IP/Domain Name" in the command line. Generally, use "ping www.baidu.com" to check whether the network is connected;

** Network disconnection Solution

Network disconnection is common for servers in the data center.
1. Check whether the NIC lights on the backend of the server are flashing properly;
2. Check the server status, whether the keyboard and mouse are responsive, and whether the system is on the logon page;
3. Enter the server and run the ping command to check whether the server can be pinged to Baidu or other Internet;
4. sometimes, the system file tcpip is caused by an illegal shutdown or virus. sys is damaged. As a result, the TCP/IP Protocol Driver driver is damaged. As a result, an unable to contact IP Driver error occurs when you ping the local return address. The solution is to restore the tcpip. sys file;

** The Windows Service option is disabled.

Occasionally, Remote Desktop Access is not supported due to insufficient resources on the server. Disabling the currently running program still cannot solve the problem. It should be caused by the running of related services in the background. You need to disable some services to release resources. If the following 12 basic services are retained, other service options are retained as needed.
By default, the DCOM Server Process Launcher System cannot stop services;
After the DNS Client resets the IP address, it does not prompt to restart the service of the machine;
One of the three services required by the Event Log system;
One of the three services required by the Plug and Play Systems;
One of the three services required by the Remote Procedure Call (RPC) system;
The Security Accounts Manager system cannot stop services by default;
Server shares services required by local files and folders;
Shell Hardware Detection is also a service required by Windows;
Terminal Services allows you to remotely log on to your local computer. This is required for Fast User Switching and remote desktop functions;
Windows Management Instrumentation is required for Windows;
Services required by Workstation to access files and folders shared by other local networks;
The service automatically started by the Windows Time Server cannot be disabled.
