My brother-in-law is starting a business and has a need for encryption protection. I have heard good things about PGP Whole Disk Encryption but I have heard that during startup it requires a password. This won't be that convenient for us since most of the maintenance work done on the server is done remotely making restarting the computer difficult from a remote location. Is there any good encryption software that does not require a password before you are logged in to windows?
