+(SSH_DISCONNECT_PROTOCOL_ERROR): "Too many authentication failures for root"}
+
+This message is produced by an OpenSSH (or Sun SSH) server if it
+receives more failed authentication attempts than it is willing to
+tolerate.  This can easily happen if you are using Pageant and have a
+large number of keys loaded into it.  This can be worked around on the
+server by disabling public-key authentication or (for Sun SSH only) by
+increasing \c{MaxAuthTries} in \c{sshd_config}.  Neither of these is a
+really satisfactory solution, and we hope to provide a better one in a
+future version of PuTTY.

-In modern versions of PuTTY, you should not see this error.

-Windows's documentation about this error condition is not very good,
-but as far as we can tell, this error occurs when PuTTY is listening
-on a port, another program makes a connection to that port, but
-closes the connection so fast that PuTTY has no time to answer it.
+This error occurs when the Windows network code decides that your
+network connection is dead. For example, it will happen if you pull
+the network cable out of the back of an Ethernet-connected computer,
+or if Windows has any other similar reason to believe the entire
+network has become unreachable.
 
-PuTTY only ever listens on a port when it is doing local-to-remote
-port forwarding (see \k{using-port-forwarding}); and if an incoming
-connection on that port receives this error, PuTTY should simply
-close the connection and continue without error.

-If you see this error in PuTTY 0.53 or above, we would welcome a
-report of the circumstances.
+We are not aware of any reason why this error might occur that would
+represent a bug in PuTTY. The problem is between you, your Windows
