{% hint style="info" %}
There is no indication from this event alone that it was installed locally on the system itself, and services may be installed remotely leveraging utilities such as `sc.exe`. In the event that the new service was installed remotely, as [EventID 4624: An account was successfully logged on](/windows-forensics/artifacts-by-type/event-log-artifacts/security/evtx-4624-successful-logon.md) event may be logged before the new service is installed with a `LogonType` of 3.
{% endhint %}

## Example

In the following example, the following command was executed on a domain controller:

```
sc.exe \\WKS10-01 create mynewservice binpath= c:\temp\example.exe start= auto displayname= "My new service"
```

This installed a new service on the system WKS10-01, generating the following [EventID 4624: An account was successfully logged on](/windows-forensics/artifacts-by-type/event-log-artifacts/security/evtx-4624-successful-logon.md) event:
