    Like MS Terminal Services, CITRIX Metaframe 1.8 (and other versions, I
    suppose) also only logs the IP informed by the client.
    
    The log, made on Windows NT Event Log, looks like this:
    
    
    ========================================================================
    Time: Wed Nov 21 09:37:00 2001
    User: MARCUS   Agent: metaframe2
    Source: Security   ID: 528   Type: Success Audit
    Successful Logon:
    	User Name:	MARCUS
    	Domain:		NTDOMAIN
    	Logon ID:		(0x2,0x2959446E)
    	Logon Type:	2
    	Logon Process:	User32  
    	Authentication Package:	MICROSOFT_AUTHENTICATION_PACKAGE_V1_0
    	Workstation Name:	WTS2
    	WinStation:	ICA-tcp#245
    	Session ID:	245
    	Client Name:	STATION2
    	Client Address:	192.168.0.44
    ========================================================================
    
    
    In a incident investigation this is a problem for trace-back the
    suspects.
