@ Vegar, вы можете использовать функции WTSEnumerateSessions и WTSQuerySessionInformation для получения этой информации.
проверьте эту ссылку для примера использования Jedi Api Headers .
проверьте этот код.

UPDATE
Как говорит @Remko, функция WTSQuerySessionInformation с типом WTSClientAddress может возвращать локальный IP-адрес клиента. если вы хотите получить настоящий ip, вы можете использовать вспомогательную функцию WinStationGetRemoteIPAddress, расположенную в блоке JwaWinSta.
Var
Port : Word;
IpAddr : WideString;
Begin
WinStationGetRemoteIPAddress(WTS_CURRENT_SERVER,WTS_CURRENT_SESSION,IpAddr,Port);
End;
