Hi baftos,
I tried to telnet remote windows machine from my local machine on port 23, its not connected and given error message like "Connect failed".
As your response, if we can telnet to remote windows machine from local machine then we can connect from Java. Is it correct ?.
Can you please help me to resolve this issue. And also please confirm the port (23) is correct, which I was used to connect remote machine from telnet.
Regards,
Praveen
