The public key on Windows needs to be placed in C:\ProgramData\ssh\administrators_authorized_keys Administrative user The contents of your public key (\.ssh\id_rsa.pub) needs to be placed on the server into a text file called administrators_authorized_keys in C:\ProgramData\ssh\. You can copy your public key using the OpenSSH scp secure file-transfer utility, or using a PowerShell to write the key to the file. The ACL on this file needs to be configured to only allow access to administrators and System.

The known_hosts and known_hosts2 messages you saw in your client are NOT the cause of your problem. If you must set your own default known_hosts file, then launch your ssh client like this: ssh -o GlobalKnownHostsFile=~/.ssh/My_own_known_hosts @ signature.asc Description: This is a digitally signed message part.
