we have configured CYGWIN on windows 2008R2 and the services are started when we try to connect from outside to the server it is giving the below error.

Could you please throw more light on what has to be done to avoid the error , like steps that i have to perform on windows 2008(where cygwin) is installed ? – vikas – 2015-01-08T12:46:10.257
@vikas he told you that you need to edit your ssh_config file. so the intelligent question you should be asking is HOW. You can look for
StrictHostKeyChecking
if it's set to yes then that's why. You could put it to no. Or you could rm the known_hosts file. You should find where these files are. look within c:\cygwin\home include subdirectories in your search – barlop – 2015-03-25T18:06:28.067@vikas and if you can't do that then look up how to search for a file in Windows. And when you have a problem don't just ask for instructions step by step. State exactly what you have done and where you are stuck. – barlop – 2015-03-25T19:19:46.637
