This is a generic error proced by the Windowsnetwork code when it kills an established connection for some reason. Forexample, it might happen if you pull the network cable out of the back of anEthernet-connected computer, or if Windows has any other similar reason tobelieve the entire network has become unreachable.
Windows also generates this error if it hasgiven up on the machine at the other end of the connection ever responding toit. If the network between your client and server goes down and your clientthen tries to send some data, Windows will make several attempts to send thedata and will then give up and kill the connection. In particular, this canoccur even if you didn't type anything, if you are using SSH-2 and PuTTY attemptsa key re-exchange. (See section4.19.2 for more about key re-exchange.)
(It can also occur if you are using keepalivesin your connection. Other people have reported that keepalives fix thiserror for them. See section4.13.1 for a discussion of the pros and cons of keepalives.)
We are not aware of any reason why this errormight occur that would represent a bug in PuTTY. The problem is between you,your Windows system, your network and the remote system.
