I turned on verbosity for the client and performed my tests- called the
batch script directly and from the seervice. Attached are the logs from
SSH client for both cases. I have removed my server name and user name
for security reasons.
Thx for your help,
Rachan

I have installed cygwin ssh client on my laptop and created a service to call a simple batch script which in turn calls ssh.exe with the required parameters. I am using RSA keys without passphrase to avoid entering password every time the service is started. The problem is that every time the service starts, it prompts for a passphrase. However, if I open a command prompt and manually call the batch script, it does not ask for a passphrase and directly log me into the server.
