Things were fine. What happened? TClientSocket error. You should provide the error code. Something like 10061 (This is a winsock error code saying "connection refused"). Yes. 10061 As I said, error 10061 is a winsock error telling that the remote computer doesn't accept the connection. This occur when the remote computer has no program accepting the connection. The server is not running if you prefer. This may also happend when there is a bug or misconfiguration in the client program. You think you connect to some remote IP/Port but actually connection is attempted on another IP/Port. So first check the server program is running on the target computer, verify that the program is running is listening on the correct port number of the interface you will conect thru. If the server is running, then check your client program. Verify that it tries to connect to the server IP using the correct port. If everything seems OK, use a sniffer to spy on the network cable and see what happend. Yousee the packets from client trying to establish the connection to the server and the packets from the server, either refusing the connection (which will result in error 10061). You'll be able to confirm the client program tries to connect to the correct IP/port. As sniffer you can use the free Ethereal. Link on the links page at my website. Contribute to the SSL Effort.

Yes. 10061 As I said, error 10061 is a winsock error telling that the remote computer doesn't accept the connection. This occur when the remote computer has no program accepting the connection. The server is not running if you prefer. I can connect to the Internet via most software programs, such as IE, Opera, Netscape, and AtomTime. When I run Delphi 5 and try to connect, e.g., to the NIST time (the same server that AtomTime connects to), I get this error. This was working fine until yesterday. I do not know what I did and how to undo it. Maybe because I reinstalled Panda. I had a crash, and had to reinstall the OS. I did it fine. My Delphi programs were connecting to the Internet. Then suddenly refuse connection.

From the command prompt, I typed telnet server 110. Could not connect. I disabled Panda anti-virus.

Maybe you have another kind of firewall program ? Contribute to the SSL Effort.

This worked in the past. I do not understand port = 13. This is the port you want to connect to. It depends on the server you want to connect to. If you select a random port, you will of course - except by chance - get a 10061 error ! You must select a correct IP address (the server's IP of course). You must select the correct port (The port the server listen on) You must select the correct protocol (TCP or UDP). What is the server ? Contribute to the SSL Effort.

The server is not running if you prefer. Reinstalled from the image on an external hard disk. Now things are working fine. What could have gone wrong? Who knows? I do not have the files anymore to investigate. It bothers me how something like this could have happened.
