When I use the new remote desktop with ssl and try to log on with bad credentials it logs a 4625 event as expected. The problem is, it doesn't log the ip address, so I can't block malicious logons in our firewall. The event looks like this:

<Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">

</Event>

It seems because the logon type is 3 and not 10 like the old rdp sessions, the ip address and other information is not stored.

The machine I am trying to connect from is on the internet and not on the same network as the server.

Does anyone know where this information is stored (and what other events are generated with a failed logon)?

Any help will be much appreciated.
