Hi,

I am new to ELK and I have an issue with my Elastic Agents on my Windows servers.

I am working with :

- Elasticsearch / Kibana version 8.4.2
- Elastic-Agent version 8.4.2

I have successfully enroll my Fleet Server (v 8.4.2) and its appears "Healthy" in Kibana.

I have also enroll my Elastic Agent on my Windows VMs with :

> .\elastic-agent.exe install --url=[https://ip-fleetserver:8220](https://ip-fleetserver:8220) --enrollment-token=token --certificate-authorities=/path/to/my/ca.crt --fleet-server-es-insecure

The Agents looks "Healthy" for several minutes but then switched to "Unhealthy", then back to "Healthy", then again "Unhealthy", etc...  
On my servers the command .\elastic-agent.exe status shows :  
`Error: failed to communicate with Elastic Agent daemon: rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing open \\\\.\\pipe\\elastic-agent-system: Access Denied."`

In Kibana, I have severals errors displaying in the Agents Logs details :

```auto

> 11:20:59.670 elastic_agent [elastic_agent][error] Elastic Agent status changed to "error": "app filebeat--8.4.3-da9ed2be: 1 error occurred:\n\t* 1 error: Error creating runner from config: Failed to create new event log. 1 error: invalid event ID query component ('')\n\n"

```

```auto

 - type: 'ERROR' - sub_type: 'FAILED'

```

```auto

```

I search the troubleshooting guide with no luck, so any help or advice would be appreciated !

Thanks !
