Windows Server hang

Question

Hello,

Win 2016 servers are installed in my environment and Sql is available on these servers. Recently, these servers occasionally hang from time to time and sql connections are broken. At the time of hang, RDP cannot be done to the server, ping can be pinged, the services of the server with hang can be accessed via another server, smb shares are also coming.

Again, when I try to enter a password on the password screen via the vm console to the server at the time of hang, it gets an error that it cannot find the domain. The server stands up after a while, this time varies from 10 minutes to 30 minutes to 1 hour.

In the log checks I made when the server stood up, 1688 event logs appear in the system logs. In this log, there are logs that the Cluster object was disable and failed when trying to enable it.

Unfortunately, no memory.dump file is created on the server.

Has anyone experienced a similar problem? I would like to ask those who have experience to share what the problem may be caused by.
