To apply a certificate that was sent to you as keyname.cer:
1. Stop the WS_FTP Server service and close Server Manager.
2. Navigate to your host's Security directory on the hard drive. If you are unsure what this is, open Server Manager and at Local System, select the Modify General System Settings button. Note the directory listed in the Security directory field. Each host on your system will have its own folder in this directory. The folder for the host should match the name of the host.
3. Make a backup of the keyname.cer that should already exist in this directory. Save the keyname.cer file sent to you by the Certificate Authority [1] in its place.
4. Open Server Manager, expand Local System and then select the SSL window under your host.
5. Verify that Certificate field is your keyname.cer you received from the CA.
6. Restart the WS_FTP Server service.
