I know you asked for native C++, but .NET has SystemInformation.TerminalServerSession. Worst case you could write a thin C++/CLI DLL that returns this value to you.

http://msdn.microsoft.com/en-us/library/system.windows.forms.systeminformation.terminalserversession.aspx[^]

[Update]

Sorry, but you don't need to use .NET at all.

See http://msdn.microsoft.com/en-us/library/aa380798(v=vs.85).aspx[^]

Code snippet from that link:

C++

#include <windows.h>
#pragma comment(lib, "user32.lib")

BOOL IsRemoteSession(void)
{
   return GetSystemMetrics( SM_REMOTESESSION );
}
