Turn Off Trace Logging for Licensing

Trace logging for licensing compliance in Windows EBS is turned on by default. Trace logs are useful in troubleshooting possible licensing compliance issues. However, at any time, you can turn off trace logging for licensing compliance and remove the log files from Management Server computer.

Windows EBS depends on two licensing services:

  • Server Infrastructure License (SIL) Service

  • Windows Server Solutions Licensing Management Service (LMS)

To completely turn off trace logging for licensing compliance, you must turn off both services, and then remove the log files for each service.


You must use an account that is in the local Administrators group to perform this task.
