I had set up a clients MARS to use SFTP archiving to a windows server. However, I found out from them that the SFTP server software was using a high amount of CPU resources on the server. A co-worker changed the SFTP server software and now the MARS will not connect to the SFTP server. He said it looks like the MARS will not accept the new SFTP server's SSH key. Is there a way to clear the old SFTP servers SSH key from the MARS?
