|This warning message is created by FKM based on the ERROR_SHARING_VIOLATION error from Windows. This happens when FKM tries to access a file but fails to display fail attributes due to the exclusive hold of outside process code.|
From the FKM User Guide:
Ensure the configuration details have been validated and the connection among your Probes, Managed entity, and the FKM sampler are working properly. The minimum requirement to read the source file is that the Netprobe user ID must have a read-access to the source file.
Installing the Microsoft Process Explorer application may help to identify which process is holding the file.
