log file (if it exists) which would store the remote IP address of the
machine that tried to break in per the below Windows Event log?:

My advice would be to see if you can duplicate the errors and then do some event correlation between your event logs and IIS logs. 

I tried (quickly) to duplicate it in my environment to no avail. 
Sorry.

Does anyone know if there is a log file, and its location, for RDP in
terms of storing the user id and IP address of login attempts?

Thank you.

Have a look in \system32\Tssdis.log, You need to enable event auditing
in the GPO and auditing in Terminal Services configuration. Cant check
myself so not sure if this is exactly what you are looking for.

Hello Peter,

These are stored in the Windows Event Log, as 682 and 683 for session
reconnected and disconnected, respectively. A 528 is logged for the
initial local logon.

Do you know what the reconnaissance, if any, looked like? Maybe you can
get the IP from firewall logs or some other service which logs the
source IP. I think you may need to do some manual correlation.

Greetings Michael:

Is the IP address of the party trying to connect via RDP stored
anywhere?

thank you.
