Yes, this is the expected behavior, and this is what you want it to do. When the remote box is reset to a default configuration (I'm assuming this means the existing files are wiped out, such as restored from a firmware backup), it loses its key
Now, if you wish, you can save the host keys, public key, and private keys, from the remote box into a secure location, then you can copy them back in place on the remote box when it is reset to a default configuration.

That is all good. However, every time the network admin resets the remote box to default configuration the key changes and I have to manually edit the host file to remove the old key. Resetting to default config on the box simply just restores the settings to factory defaults. Is this expected behavior? What defines a fingerprint? Thanks, Amit
