Solution to the problem of Windows Server 2008 r2 server automatically restarting for no reason

Windows Server 2008 server automatically restarts! After logging in to the server, no matter what operation you perform, the server will automatically restart in one or two minutes.

English version system

Chinese version system

Click Settings under Startup and Recovery to see:

Uncheck Automatically restart in the image and save the file.

Whether you click Users or Groups, the system will prompt:
“Windows has encountered a critical problem and will restart automatically in one minute. Please save your work now.”

Clicking "User Account" under "Control Panel" will also prompt "Windows has encountered a critical problem and will restart automatically in one minute. Please save your work now."

After installing 360 and scanning the server, I found a win32.trojan Trojan, but after deleting it, it remained the same. Finally, I thought of checking the registry and found that all the users were there, but there was an abnormal user named admin$, who was also an administrator:

After comparing with other servers, I found that there was no such account, so this should have been created by the hacker after the server was invaded, so I deleted it in the registry. Later, I found that clicking on the user account was normal, so all accounts can be displayed:

The editor of 123WORDPRESS.COM adds: Other problems like this are generally caused by poor server security. You can install an account locking tool, such as mcafee, Safe Dog, and many other tools.
