Please follow this steps.

1) Open Event Viewer.

2) Security Logs Properties.

3) Select Below radio Buttion.

I have checked this and all the PCs are set to overwrite events as needed, It definitely happened straight after the update of SEPM clients to version 12.1

Hi Ashish

Thanks for the information, but I have explored all these options and most of our PCs are running the latest service pack and we cannot apply this hotfix as it was released in 2003 after SP1 had some issues. How did your problem get fixed?

Hi,

For testing purpose Remove SEP client on machine and check Logs are created or not ?

Do you have installed the 3rd-party softwares such as McAfee

Failure Audit, Security, Privilege Use, Event ID 577 (displayed on client after installing McAfee Agent 4.5)

are you referring to Microsoft security log, then agree with the above comments. You may test it if you uninstall SEP agent on one machine and monitor for the logs.
