PRTG Remote Probe Npcap issues
PRTG (Npcap) Wednesday, 17 July 2019 by paul

Recent versions of PRTG Network Monitor have started including the Npcap driver for packet capture. This driver is causing issues when installed onto machine with 4G connections - disabling their 4G connection until the loopback adapter is disable or uninstalled.

Paessler support have recommended removing the driver and will modify their remote probe installs in future releases of PRTG.

The batch file below will silently uninstall the Npcap drivers.


Rem Remove Npcap

IF EXIST "c:\Program Files\Npcap\uninstall.exe" goto USTART
IF EXIST "c:\Program Files\WinPcap\uninstall.exe" goto USTART

net stop prtgprobeservice

IF NOT EXIST "c:\Program Files\Npcap\uninstall.exe" goto NONPCAP
"c:\Program Files\Npcap\uninstall.exe" /S

IF NOT EXIST "c:\Program Files\WinPcap\uninstall.exe" goto NOWINPCAP
"c:\Program Files\WinPcap\uninstall.exe" /S

Ping -n 30

net start prtgprobeservice

Latest release of PRTG Server no longer creates the loopback adapter - https://www.paessler.com/prtg/history/stable#
