[/Policy:{AdminApproval | Disabled}]   Specifies how and when to respond to
                                        client computers.
                                        AdminApproval means unknown
                                        computers will be put in a pending
                                        queue (in the Pending Devices node
                                        of the MMC snap-in). The install
                                        will not proceed unless the admin
                                        approves the boot request.
                                        Disabled means that administrator
                                        approval is not required.
 [/PollInterval:{Time in seconds}]      Interval (in seconds) at which the
                                        network boot program should poll the
                                        WDS server.
 [/MaxRetry:]                  The number of times the network
                                        boot program should poll the WDS
                                        server. This value, along with the
                                        PollInterval, dictate how long the
                                        network boot program will wait for a
                                        administrator to approve/reject the
                                        computer before timing out. For
                                        example, /MaxRetry:10 and
                                        /PollInterval:60 means the client
                                        should poll the server 10 times,
                                        waiting 60 seconds between each try.
                                        Therefore, the client would timeout
                                        after 10 minutes (10 x 60 = 600
                                        seconds, or 10 minutes).
 [/Message:]                   The message displayed to users that
                                        are in a pending queue.
 [/RetentionPeriod]                     The number of days a device can remain
                                        in the Auto-Add database before
                                        being purged.
  [/Approved:]            Retention period for approved devices.
  [/Others:]              Retention period for unapproved
                                        devices (rejected or pending).
[/AutoAddSettings]                      Specifies the default settings for
                                        each computer.
 /Architecture:{x86 | ia64 | x64}       Specifies the architecture for these
                                        settings.
  [/BootProgram:]        The network boot program to send to the
                                        approved computer. If not specified,
                                        the default for the architecture
                                        will be used.
 [/WdsClientUnattend:]   The path to the unattend file that the
                                        approved client should receive.
 [/ReferralServer:]        The WDS server the client should
                                        download boot and install images from.
 [/BootImage:]           The boot image the approved client
                                        will receive.
