Hello Ronaldo,
10053 is when OS decide to stop the connection. Normally this is because
of some network problem, a malfunctioning router or switch. But many
virus scanners and firewalls are doing wierd things with TCP, so stop
any service of it (not disable it) and test again.

I don't see anywere in your code logging of the ErrCode argument in the
TWSocket events! So it is not sure where you get the error 5
I also see you use OnError event of TWSocketServer and use GetLastError
there. Don't use OnError, instea
here is code
##
type
TForm3 = class(TForm)
Socket: TWSocket;
Server: TWSocketServer;

Hello Ronaldo,
As Arno already sayed this is not a winsock error. But to be sure
(because I don't see it in your code example), we are talking about the
ErrCode argument in the TWSocket events, right?

Sounds like the Windows system error code "ERROR_ACCESS_DENIED".

Hello Ronaldo,
At first sight I see nothing wrong with your code. However it is not
normal that some of the sockets close without reason. Wich of the
sockets do the close? Maybe the close is with a winsock error, then it
will tell you more about the reason. You have at least log all the
winsock er

Hello,
I have a TWSocket who connects to a printer.
What's the best way to detect a broken connection.
TWSocket is only waiting for data from the printer (special printer...)
therefore I do a TWSocket.connect.
When the printer is Offline (power off for example) after the connection is

Hello Abdullah,
You can check winsock error in OnSessionClosed of your client program.
If it does have an error and you never call Close(Delayed) in your
client then you can assume that server close connection.
If you have errorcode then possible it is due to data loss or some
firewall interferin

Hi,
This is my first post to the list so I hope I do it right. My question
is as follows: I'm trying to code a simple FTPServer using the ICS Demo
as a base. However, I want to be able to disconnect a user via the
server. I see the "FtpServer1.Disconnect()" method but I don't know how
to use it. C
NOOP is a good one.

Hello,
I've already written in this maling list about disconnect from FTP

solving this problem, so I ask help again.
The steps are:
