I've been having the exact same problem for some time (except I'm on Windows
2000 rather than 2003).
Today I tried doing 'net stop sshd', then 'cygrunsrv -R sshd', then I
renamed my C:\cygwin directory to C:\cygwin.renamed, then downloaded the
latest copy of setup.exe and installed from scratch (to C:\cygwin),
selecting openssh (and of course its automatic prerequisites) as the only
non-default package.
Then did ssh-host-config and told to it use privilege separation and install
sshd as a service, and gave "ntsec" as the value of CYGWIN.
I then rebooted, but the problem was still there. Trying to ssh into my
cygwin box gives the:
ssh_exchange_identification: Connection closed by remote host
error on the client. /var/log/sshd.log on my cygwin box contains:
13 [main] sshd 1144 child_copy: linked dll data write copy failed,
0x33F000..0x33F050, done 0, windows pid 2276708, Win32 error 487
Do a 'net stop sshd' and a 'net start sshd', and then I can connect in fine.
sshd started up at boot time just fine for years on this box. I believe the
issue started occurring when I upgraded from Cygwin 1.5.18-1 to 1.5.21-1,
but it might have been an openssh upgrade instead that started causing the
problem. I have had at least a couple of different openssh version updates
on here since I started having the problem (most recently 4.4p1) and it is
still occurring.
Help...? ;^>
