Good Day I would really appreciate it if someone can assist me.
I have a Windows server 2003 server with the latest Cygwin installed. CYGWIN_NT-5.2 2.5.2(0.297/5/3) 2016-06-23 14:27 i686 Cygwin I have setup the SSH service as I have many a time before on other servers. The service successfully starts however I cannot SSH into the machine and am presented with the following error: ssh_exchange_identification: read: Connection reset by peer Note that I have allowed it through the firewall and this error is even present on the machine itself $ ssh -vvvv localhost OpenSSH_7.3p1, OpenSSL 1.0.2h 3 May 2016 debug1: Reading configuration data /etc/ssh_config debug2: resolving "localhost" port 22 debug2: ssh_connect_direct: needpriv 0 debug1: Connecting to localhost [127.0.0.1] port 22. debug1: Connection established. debug1: identity file /home/Marcel/.ssh/id_rsa type 1 debug1: key_load_public: No such file or directory debug1: identity file /home/Marcel/.ssh/id_rsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/Marcel/.ssh/id_dsa type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/Marcel/.ssh/id_dsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/Marcel/.ssh/id_ecdsa type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/Marcel/.ssh/id_ecdsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/Marcel/.ssh/id_ed25519 type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/Marcel/.ssh/id_ed25519-cert type -1 debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_7.3 ssh_exchange_identification: read: Connection reset by peer There are no hosts.allow or hosts.deny files present on this machine and Cygwin has been reinstalled several times under different users to test permission theories I had. When I change the permission of the /var/empty folder to my current user to allow me to run the sshd Daemon as my current user I see the following: $ /usr/sbin/sshd -ddddd debug2: load_server_config: filename /etc/sshd_config debug2: load_server_config: done config len = 288 debug2: parse_server_config: config /etc/sshd_config len 288 debug3: /etc/sshd_config:19 setting Protocol 2 debug3: /etc/sshd_config:43 setting PermitRootLogin yes debug3: /etc/sshd_config:53 setting AuthorizedKeysFile .ssh/authorized_keys debug3: /etc/sshd_config:79 setting KerberosOrLocalPasswd yes debug3: /etc/sshd_config:109 setting UsePrivilegeSeparation yes debug3: /etc/sshd_config:125 setting Subsystem sftp /usr/sbin/sftp-server debug1: sshd version OpenSSH_7.3, OpenSSL 1.0.2h 3 May 2016 debug1: private host key #0: ssh-rsa SHA256:eH6f4o7GOW6xajSHXQywMtsWmocl4PzgNy6o1Dmbxoc debug1: private host key #1: ssh-dss SHA256:pZxX5Ddzn6mR5sOlRPjNV3mtXgJTSpZjkSgpySz0wsI debug1: private host key #2: ecdsa-sha2-nistp256 SHA256:dyTs9OY0gaXfEv09jx3DZYlgEUjBQKKGkQJ/ioTG2qQ debug1: private host key #3: ssh-ed25519 SHA256:KeIpfsnyBDf2V7OH9BFjx8xmhh/HwqJ2QUOyUPy6hsM debug1: rexec_argv[0]='/usr/sbin/sshd' debug1: rexec_argv[1]='-ddddd' debug2: fd 3 setting O_NONBLOCK debug1: Bind to port 22 on 0.0.0.0.

I have attempted numerous modifications of the setup and daemon config, eventually just to confirm all networking aspects are correct I installed bitvise ssh server and this worked, however I really need to get Cygwin working correctly. I have also tried changing the default port to 2200 but all yield same result. Any Ideas?
