Hi,  
I'm working at the moment correlating windows Logon and Special Logon events (4624 and 4672) .  
I want to drop the events 4624 event when `event_data.TargetUserName` ends with $ because is a computer-related account joining the domain.  
What I have done so far is not working and I'm still receiving those events.

1. First I 've put the drop\_event processor before the script processor, so the field I'm looking at is event\_data.TargetUserName, not user.name  
Is this correct?

2. I've tried with the regexp condition, and no luck

also I've tried with an specific user, still no work (instead of the regexp line)

```
         - contains:
              event_data.TargetUserName: "DC_TEST2K12$"

```

What I'm doing wrong?  
Thank you very much  
Regards  
Ana

Apparently is working now. I was using the wrong field name is winlog.event\_data.TargetUserName instead of event\_data.TargetUserName
