hello All,

Good day,

We have configured active-response for windows machine as suggested in 
http://www.ossec.net/doc/manual/ar/ar-windows.html

while executing *agent_control -b 1.2.3.6 -f win_nullroute600 -u 001* we 
are getting response below and we are also getting the null route added for 
the ip address 1.2.3.6 in target machine

*agent_control -b 1.2.3.6 -f win_nullroute600 -u 001*

OSSEC HIDS agent_control: Running active response 'win_nullroute600' on: 001

However, when someone trying to make unauthorized access then at that time 
the active response seems not working because we are still getting multiple 
login failure message with following details.

Rule: 18152 fired (level 10) -> "Multiple Windows Logon Failures."
Portion of the log(s):

WinEvtLog: Security: AUDIT_FAILURE(4625):

any clue ?

is there other way to know if active response is working or not ?

thanks
