Our Eventlog Analyzer Server stopped displaying windows event logs. It stopped on the 15^th last month, but we did not make any changes.

We have agents installed on new windows domain attached system I created today, existing windows workstations/windows servers attached to the domain, and two stand-alone windows systems.

 The syslog devices(RHEL) and FIM records are reporting fine.

 Does anyone know of what possibly could be causing the issue?
