Technet article Q140714 lists the different logon Event Viewer message types. Here is the list:
Interactive logon Event ID 528 Type 2
Interactive logoff Event ID 538 Type 2
Network logon Event ID 528 Type 3
Net Use connection Event ID 528 Type 3
Network logoff Event ID 538 Type 3
Net use disconnection Event ID 538 Type 3
Autodisconnect Event ID 538 Type 3
Unfortunately, this is not gonna help you much! I just did a TS connection to a server, and it wrote in the server's Security log Event ID 528 Type 2.
Now, when I log into my workstation, it ALSO writes Event ID 528 Type 2.
So, looks like a TS connection is treated the same way as a normal login when you are standing at the box! So, this is not the news you were looking for.
Sorry for not having good news.
