Hi,
Did anyone successfully retrieve the client IP address on a
terminal-server (RDP)?
How?

Thank you, Jose.
But where can I find WTSsessionInformation class?

Hi,

Attached to my answer is the code. I can not find it?

I'll send it again anyway.

Regards. Diego

Thank you, Diego!
Seems like it would work.
Where do I find OT4XB?

Thank you, Jose!
It is working great, but I was looking for the local-public IP of the
client, not the local-internal one.
Is there a way to get the local-public IP (to enable http call back to
the client's network)?
Many thanks,
-Itai

Hi Itai:
good day.
Please see if this is what you are looking for.

Thank you, Carlos, but this PRG is not what I am looking for.
I am trying to get the public IP of an RDP client (not 192.168.x.x).
It seems the solution is somewhere in the API Wtsapi32.dll, but I
could not find it.

(BTW IP.PRF requires several *.CH files which I do not have).
I will try to open a new thread for this.
Again, many thanks for sharing the IP.PRG.

Carlos,
None of the functions in that link can be used to show the
local-public IP.
I know the server has it because netstat is showing it (along with all
other connections), but I could not find the API that exposes that IP.

Hi Itai:
my last try to get the text created below (using RunShell() or other):
ping.exe -4 + HostName > RemoteIP.txt

Beling,
I do not understand this.
Ping requires a valid IP or URL.

Hi Itai
I attached what I am using.
I do not remember how I got it.
Please see it.

Beling,
Does it show the remote-client IP or the local server IP?
Could you please post CabDefs.ch as well?
Thanks,
-Itai

Hi Itai:
good day.
I do not understand many things about internet communication, but I got 
somewhere things contained in this attach and I hope that this is what 
you are looking for. If it is not, excuse me to make you loose your time.
In time: excuse the bad code that I wrote and, if you need, I have the 
complete headers files used (they are big) and can seek for other things 
that you may need among that things that I had collected.

Thank you Beling.
This program shows the public IP of the computer on which it is
running.
In the case of terminal-server, the program runs on a server, but we
need to know the public-IP of the client connected to that server.
I'll post a solution when I find it at the upper thread.

Again, thank you for your help.

Hi Itai:
I thought that the comment below could to have a clue for the solution 
of the problem:

      You can get the external IP address of your computer only from 
the outside
          world. There is no way to determine if it is a static or 
dynamic IP address,
          though.
      There are several services that will tell you what your IP 
address but they don't
            always work and change over time.
      If they fail you can to make a Google search like "what is my IP"
      The services may return a html where the IP is inside and you 
need to parse it for to get the IP.

Beling,
The terminal-server is at the "outside world".  Each client's
connection is set on a specific outgoing port linked to the client's
public IP.  That connection can be viewed via NatStat.  But it seems
that Microsoft did not [yet] develop an API that exposes the
connection of each session.  Thus, my search for such API is
[currently] unsuccessful.  I should resolve this problem in a
different way.
