*Enbironment
-zabbi version
zabbix-2.0.14

-zabbix server
CentOS 6.5

-zabbix agent
Windows Server 2008 R2 Standard SP1 64bit

*Problem
1.Make a target server maintenance mode by maintenance plan.
2.Make windows eventlog errors on the server and then reboot it.
3. When the maintenance plan term is over, all the windows event log errors are detected as error and alerted.

This problem occurs both the maintenance plan configured with data correction is on and off.
Event log detection function is working correctly except for the problem.

How can I prevent this problem by zabbix itself with no other 3rd party application's help?
