Hi,

re-read search syntax post serveral times over - still unable to do what I need.

Here's the situation: Gathering logs from windows event log, have lots iwth event id 4625 and in some cases the event\_data.TargetUserName is a machine (having at the end of the name, like CPU1, MACHINE2$ etc).

I want to find all records with event\_id:4625, but the not the machine accounts.

Here is what I have tried (with no success) - problem seems to be escaping dollar sign.  
event\_id:4625 NOT event\_data.TargetUserName:"_" event\_id:4625 -event\_data.TargetUserName:"\*"  
event\_id:4625 NOT event\_data.TargetUserName:/(._)$/ (and several other options)

Anyone facing similar problem?  
Thanks, J
