Good day all.  It seems like I'm seeing a very odd issue with regard to 
Windows events coming through to the OSSEC management server.  I've set 
this up before without any configuration changes & received all the events 
I wanted from the Windows end point (a Win7 machine), but this time around 
(a Win2k3 Server for testing) it seems to be failing as far as what data it 
returns into the main alerts.log file.  Here's a sample of one of the 
events I get:

** Alert 1402320160.117595: mail  - syslog,errors,
2014 Jun 09 09:22:40 (SERVER) 10.0.0.10->WinEvtLog
Rule: 1002 (level 2) -> 'Unknown problem somewhere in the system.'
2014 Jun 09 09:22:40 WinEvtLog: Security: AUDIT_FAILURE(529): Security: 
SYSTEM: NT AUTHORITY: SERVER: Logon Failure:     Reason: Unknown user name 
or bad password     User Name: username     Domain: DOMAIN     Logon Type: 
10     Logon Process: User32       Authentication Package: Negotiate     
Workstation 
Name: WORKSTATION     Caller User Name: SERVER$     Caller Domain: DOMAIN   
  Caller Logon ID: (0x0,0x3E7)     Caller Process ID: 1364     Transited 
Services: -     Source Network Address: 10.0.01     Source Port: 58985

This event is of course generated because my RDP client doesn't store the 
password for my session, hence triggering this alert because I must be 
prompted for my password to login.  That said, I don't receive any others 
except events like this:

** Alert 1402320392.118323: mail  - syslog,errors,
2014 Jun 09 09:26:32 (SERVER) 10.0.0.11->WinEvtLog
Rule: 1002 (level 2) -> 'Unknown problem somewhere in the system.'
2014 Jun 09 09:26:31 WinEvtLog: Security: AUDIT_SUCCESS(680): Security: 
Administrator: SERVER: SERVER: Logon attempt by: 
MICROSOFT_AUTHENTICATION_PACKAGE_V1_0    Logon account: Administrator   
 Source Workstation: WORKSTATION    Error Code: 0x0

After seeing such a sparse return on Windows login/logout etc. I started 
tweaking the decoders a bit to see if that would help, but I don't want to 
go too far down the rabbit hole at this point.  Appreciate any guidance.
