Summary :
The SAP Note addresses an issue where sapevents.dll, essential for SAP services running on Windows operating systems, becomes locked in the DIR_CT_RUN directory due to erroneous EventMessageFile registration. This registry snag prevents easy replacement or update of the DLL file, impacting system operations. Remediation involves editing the Windows Registry to correct the EventMessageFile path to point to each instance’s local DIR_EXECUTABLE. Additionally, should manual unlocking be necessary (for instance, during a kernel update), the Note provides precise instructions for renaming the locked sapevents.dll using Windows Command Prompt and ensuring service restarts via SAP MMC or administrative tools for proper system function.
