So I just opened 3389 (for testing) and attempted to remote in from outside
using incorrect credentials, the event is still 4625, HOWEVER, it is not logon
type 10 (as the previous entries are ) it was a type 3
So now I'm really confused as I was under the impression that type 10 was RDP,
but clearly from my test RDP is TYPE 3

Logon Type 10 – RemoteInteractive
When you access a computer through Terminal Services, Remote Desktop
or Remote Assistance windows logs the logon attempt with logon type 10
which makes it easy to distinguish true console logons from a remote
desktop session.

Hi all,
Have an internet facing time-clock server , the network firewall has port 80
ONLY forwarding to the server,
i'm starting to see hundreds of event 4625's coming from global IP addresses
(China, Malaysia, russia etc,,)
If the firewall only has port 80 forwarded, how are they attempting RDP (Logon
Type 10)
here is one such example;
An account failed to log on.
