Simply filters the log to relevant info, not the solution.
Produces a LOT of results.

Here's what we're looking for:

<EventID Qualifiers="">4648</EventID>
<TimeCreated SystemTime="2019-11-19 12:21:45.754591"></TimeCreated>
<Computer>DC1.elfu.org</Computer>
<Data Name="TargetUserName">supatree</Data>
<Data Name="IpAddress">127.0.0.1</Data>


<EventID Qualifiers="">4624</EventID>
<TimeCreated SystemTime="2019-11-19 12:21:45.755442"></TimeCreated>
<Computer>DC1.elfu.org</Computer>
<Data Name="TargetUserName">supatree</Data>
<Data Name="LogonType">3</Data>
<Data Name="IpAddress">127.0.0.1</Data>
