Domain Controllers - Sensor has issues with packet capturing component
Microsoft
MicrosoftThe 'Sensor has issues with packet capturing component' health alert can mean several things.
It could be that you are still using the winpcap driver, you have an old version of npcap (less than 1.0), or the npcap installation doesn't contain the settings we require.
See https://learn.microsoft.com/en-us/defender-for-identity/health-alerts#sensor-has-issues-with-packet-capturing-component for more details on each.
The probable best solution would be to remove the sensor, remove any winpcap or npcap installations (please verify first that you don't need them for a different software installed on the server), and thein reinstall the sensor package. It will take care of the capturing component installation and configuration.

- I am running version 2.203.16523.48348 on the machines. I only recently installed the sensors so they have never ran a version that had winpcap. I am looking for things to try. The error doesn't give much in the form of information.

I suggest you open a support case; they will help you identify the issue.
My guess is that there was a prior version of winpcap/npcap when you installed the sensor, so it skipped installing and configuring npcap. This can be determined by the alert severity:
Low = winpcap is installed
Medium = npcap 0.x is installed
High = npcap >= 1.0 is installed, but with not with the required configuration
