1、System blue screen, frequent crashes, restarts, slow response speed
The hardware structure and operating system of the server are very similar to those of our ordinary computers. Therefore, just like our computers, they may be infected with viruses, crash, blue screen, restart, and other failures due to system vulnerabilities, software conflicts, and hardware failures. They may also be unresponsive due to excessive garbage cache information.
2、Remote Desktop connections exceed the maximum number of connections
Since the server defaults to allowing 2 connections, if you forget to log off after logging in and close the remote desktop directly, the server recognizes that this login is still left on the server side. The most common occurrence of this situation is to restart the server. However, if it is during peak hours, the losses caused by restarting the server are obvious. At this point, you can use the mstsc/console command to forcibly log in. Open the “Run” box and type “mstsc/v: xxx.xxx.xxx.xxx (server IP)/console” to forcibly log in to the remote desktop.
3、Files that cannot be deleted
How to clean up This may be because the file is still running, so you can restart and delete it, or run CMD. Enter the name of the folder you want to delete by entering arrtib-a-s-h-r, and finally enter the name of the folder you want to delete by entering del. After running this command, it cannot be restored. Please use it with caution.
4、System Port Hazards
For servers, the first priority is to ensure stability and security. Therefore, we only need to ensure the most basic functions of the server, just like sound cards are prohibited by default. We don’t need too much functionality or port support. Some unnecessary and high-risk ports can be sealed off. For some necessary and risky ports, such as 3389 and 80, we can set them as non special secret ports by modifying the registry, so that the security risks of server ports no longer exist.
Common server failures and corresponding solutions Generally, servers rarely encounter problems. Once problems occur, how can we actively rescue them? “We cannot sit idly by because once the server fails, all websites on that server will be unable to open.”. For an enterprise, websites are their lifeblood, and the losses are enormous. It was also a devastating blow for SEOER, which finally appeared on the homepage of a search engine but disappeared without a trace due to a server failure.
