Hi,
For some reason, I am failing to get any network monitoring data into my environment. I can successfully retrieve perfmon, script data, REST, and HEC. But as soon as I create a stanza with [WinNetMon://bla] nothing happens.
This is the stanza I am now using. I am actually looking for a different process but this process is always present.
[WinNetMon://lsass]
disabled=0
addressFamily=ipv4
direction=inbound;outbound
interval=60
protocol=udp;tcp
index=uf_process
process=lsass
packetType=accept;connect;LostPacket
I even tried the minimum.
[WinNetMon://lsass]
disabled=0
index=uf_process
The app is deployed with the Windows Deployment server and it lands on the client just nicely.
On the client, I pulled the following from the splunkd.log.
09-22-2020 13:57:29.780 +0200 ERROR ExecProcessor - message from ""C:\Program Files\SplunkUniversalForwarder\bin\splunk-netmon.exe"" splunk-netmon - NetmonStartDriver - StartService failure for splknetdrv! Error = -2144206839

This shows up after the restart of the UF on the client. I can't seem to find the solution to this one?
I tried to change the service the UF is running under from LOCAL SYSTEM ACCOUNT to a named account with local admin rights but it did not make any difference. It almost looks like the Windows client is missing something. This morning I removed the universal forwarder and installed the latest version. Still nothing.
