We have set up Cygwin on Windows 2012 and the services related to the tool are running fine on the server.
During installation we have created a local user cyg_server, we tried to create home folder with cyg_server using sftp cyg_server@servername but in this case when we try to do sftp -v cyg_server@servername it is prompting for the password which we have entered and the connection established home it immediately getting closed with the below result.

can you connect using WinSCP? it may provide more meaningful logs. From what I'm seeing in your logs, the failure is there, but no information as to the cause, which looks like it dumped to stdErr. you can try redirecting stderr to a file, with:
ssh -v cyg_server@fn002dataaege-n.fn.ae.ge.com 2> error.log. after it fails look at ~/error.log and see if there is more meaningful debug info on the failure. – Frank Thomas – 2015-02-26T13:02:18.853in the event logs i could see the event id as 0 and the description as below – vikas – 2015-02-26T13:08:49.050
The description for Event ID 0 from source sshd cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
sshd: PID 4376: syslogin_perform_logout: logout() returned an error – vikas – 2015-02-26T13:09:16.563
I'd try testing your configuration using PuTTY or WinSCP, to confirm that the server is working correctly. – Frank Thomas – 2015-02-26T14:01:56.573
tried with different client putty as well as secure shell i get the same result, am able to give the password but it gets immediate disconnect – vikas – 2015-02-26T16:08:06.967
could anyone please help here ? – vikas – 2015-02-27T11:02:02.817
did you run the command in my first comment, and then check the log of STDErr? Not the event log. – Frank Thomas – 2015-02-27T13:56:14.710
i have run the command ssh -v cyg_server@fn002dataaege-n.fn.ae.ge.com on cygwin bash below are the results that it displayed – vikas – 2015-02-27T15:25:19.340
