This article applies to PRTG Network Monitor 19 or later

Use Windows credentials of parent device with Chromium

This is an error that occurs on some systems only. It indicates that Chromium was not able to delete temporary files. If you face this error message,

  • either use one of the other browser engines in the sensor's settings,
  • or set the Security Context setting of the sensor to Use Windows credentials of parent device.

When you use the Windows credentials of the parent device, make sure that you enter valid credentials in the Settings tab of the PRTG device your sensor is running on. The Chromium engine will then no longer run under the Windows user account that your PRTG probe is running on (by default, this is the local Windows "system" user account), but will run as the user you define.
