You can choose one of two installation options when installing Windows Services for UNIX: standard installation or customized installation.
The following table shows which components are installed on a computer as part of the standard installation (Standard) and which additional components are available as part of a customized installation (Custom). If you select the customized installation, you can choose not to install components that are automatically installed as part of the standard installation. The designation "N/A" indicates that the component is not available on the specified operating system. For more information about these components and their dependencies, see Getting started.

Network file system (NFS) users can be authenticated using either Windows domain accounts or local accounts on the Windows server. Server for NFS Authentication must be installed on all domain controllers in the domain if NFS users will be authenticated using domain accounts. Server for NFS Authentication is always installed on the computer running Server for NFS.
Although you cannot install Windows Services for UNIX Telnet Server on a computer running Windows XP, you can use Services for UNIX Administration to manage the Telnet server that is included with Windows XP.
If you are upgrading from Windows Services for UNIX version 2.0 or Microsoft Interix version 2.2, all installed components will be upgraded.
