If the file was modified and then the check out was undone, did the user choose to overwrite his changes, keep them, or merge them with the latest version in the VSS database?
Yes, you are correct, the remote host in this case is the client. What the server log is showing is that an Undo Check Out was started and then suddenly the connection to the client was lost - which would happen if the client crashed and the socket therefore closed unexpectedly.
