Getting IP-Address.

I wanna get the IP-Address of a client-computer which create a process.

For example, a client-computer(IP:123.123.123.1) connected to NT-Server by
using Telnet-service.
And then, client-computer execute a process(test.exe : exist in
NT-Server).
In this situation, I(NT-Server) want to know IP-Address of client-computer
that executed test.exe.
Is this work could be achieved in the ProcessNotifyRoutine? Then How?

Any answer’ll be great appreciated!

Best regards.
