Universal Forwarder not sending Directory Service and other logs.

I have uploaded a Universal Forwarder to my Windows VM and configured both the inputs.conf and outputs.conf. I can confirm that the outputs.conf is working because the following logs are showing up in splunk:

[WinEventLog://Application]
disabled = 0

[WinEventLog://Security]
disabled = 0

[WinEventLog://System]
disabled = 0


However, logs under Applications and Services Logs are not showing up:

[WinEventLog://Directory Service]
disabled = 0

[WinEventLog://DNS Server]
disabled = 0



I have checked the Event Viewer to confirm that there are logs. The only difference that I see is that in the Event Viewer, the logs that are showing are in the path: Event Viewer (Local) -> Windows Logs -> 
and the ones that are not showing are in the path: Event Viewer (Local) -> Applications and Services Logs ->

my inputs.conf file:

host = <full computer name>

[WinEventLog://Application]
disabled = 0

[WinEventLog://Security]
disabled = 0

[WinEventLog://System]
disabled = 0

[WinEventLog://Directory Service]
disabled = 0

[WinEventLog://DNS Server]
disabled = 0

Do you have any other app or add-on configured with the inputs.  Run the following to see all inputs that may be present on your forwarder 

$SPLUNK_HOME$/bin/splunk btool inputs list --debug

Please specific the parameter for both stanzas as below shown and let me know how did you apply the inputs.conf? Via the deploymentserver or locally? Please share the whole path of the settings.

 

[WinEventLog://Directory Service]

checkpointInterval = 5
current_only = 0
disabled = 0
index = <your_index>
start_from = oldest



[WinEventLog://DNS Server]

checkpointInterval = 5
current_only = 0
disabled = 0
index = <your_index>
start_from = oldest

Made the changes but still didn't see the logs go through. I am setting up the inputs.conf file on the Windows VM locally and then restarting the Splunk Forwarding Service afterwards to see the changes. 
Here are the settings and path:

C:\Program Files\SplunkUniversalForwarder\etc\system\local\inputs.conf

host = <Full Computer Name>

[WinEventLog://Application]
disabled = 0

[WinEventLog://Security]
disabled = 0

[WinEventLog://System]
disabled = 0

[WinEventLog://Directory Service]
disabled = 0
checkpointInterval = 5
current_only = 0
disabled = 0
index = main
start_from = oldest

[WinEventLog://DNS Server]
disabled = 0
checkpointInterval = 5
current_only = 0
disabled = 0
index = main
start_from = oldest

[perfmon://Network Interface]
disabled = 1

[perfmon://CPU Load]
disabled = 1

[perfmon://Available Memory]
disabled = 1

[perfmon://Disk Space]
disabled = 1



Another problem I am noticing is that even though I disabled the perfmon logs, they still show. Not a big deal but it might help diagnose the root problem.

Okay, the inputs.conf looks okay. The index main is definitely empty even if you search alltime?

Could you check the internal logs on the affected Splunk Universal Forwarder for any issues?
