Some Sharing settings may not be preserved when performing an Archive and Install installation of Mac OS X 10.5 Leopard, or when migrating from a previous version of Mac OS X to Mac OS X 10.5.
This can happen if sharing services such as Remote Login, Windows Sharing, or FTP Access were enabled within the Sharing preferences on the previous system before the Mac OS X 10.5 installation; they will not be enabled in the Mac OS X 10.5 once the migration or installation is complete.
