Microsoft say this about Winsock error 10053 - WSAECONNABORTED:

An established connection was aborted by the software in your host computer, possibly due to a data transmission time-out or protocol error.

Full details of Winsock TCP error 10053 - WSAECONNABORTED:

Berkeley description: A connection abort was caused internal to your host machine. The software caused a connection abort because there is no space on the socket's queue and the socket cannot receive further connections.

WinSock description: Partly the same as Berkeley. The error can occur when the local network system aborts a connection. This would occur if WinSock aborts an established connection after data retransmission fails (receiver never acknowledges data sent on a datastream socket).

TCP/IP scenario: A connection will timeout if the local system doesn't receive an (ACK)nowledgement for data sent. It would also timeout if a (FIN)ish TCP packet is not ACK'd (and even if the FIN is ACK'd, it will eventually timeout if a FIN is not returned).

User suggestions: There are a number of things to check, that might help to identify why the failure occurred. Basically, you want to identify where the problem occurred.

• Ping the remote host you were connected to. If it doesn't respond, it might be off-line or there may be a network problem along the way. If it does respond, then this problem might have been a transient one (so you can reconnect now), or the server application you were connected to might have terminated (so you might not be able to connect again).
• Ping a local host to verify that your local network is still functioning (if on a serial connection, see next step)
• Ping your local router address. If you're on a serial connection, your local router is the IP address of the host you initially logged onto with SLIP or PPP.
• Ping a host on the same subnet as the host you were connected to (if you know one). This will verify that the destination network is functioning.
• Try a "traceroute" to the host you were connected to. This won't reveal too much unless you know the router addresses at the remote end, but it might help to identify if the problem is somewhere along the way.
