Issue/Introduction

SEP Clients showing old definitions on the SEPM, though it's updated with latest defs on client.

Environment

Cause

SEP clients sends Opstate (operational State)  to the SEPM in the form of *.dat file, which SEPM processes and puts in the database, then you see the clients correct information on the SEPM and in the SEPM logs/reports.
- The *.DAT files are not processed by the SEPM and it converts into *.err files, thus the clients information is not updated on the SEPM.
