You can delegate the ability  to attach the server to a nonadministrative group or user, which is a  feature I find pretty neat from the deployment perspective.<\/li>\n<\/ol>\n<p>During this first stage, the wizard records all data about the RODC  that will be stored in the distributed Active\u00a0Directory database, such  as its domain controller account name and the site in which it will be  placed. This stage must be performed by a member of the Domain Admins  group. The administrator who creates the RODC account can also specify  at that time which users or groups can complete the next stage of the  installation.<\/p>\n<p>The next stage of the installation can be performed in the branch  office by any user or group who was delegated the right to complete the  installation when the account was created. This stage does not require  any membership in built-in groups, such as the Domain Admins group. If  the user who creates the RODC account does not specify any delegate to  complete the installation (and administer the RODC), only a member of  the Domain Admins or Enterprise Admins groups can complete the  installation.<\/p>\n<p>During the second stage, the wizard installs AD\u00a0DS on the server that  will become the RODC and attaches the server to the domain account that  was previously created for it. This stage typically occurs in the  branch office where the RODC is deployed. During this stage, all AD\u00a0DS  data that resides locally, such as the database, log files, and so on,  is created on the RODC itself.<\/p>\n<p>At this point of the installation process, we can specify any group  or user who will later be able to install and manage the RODC. As we are  not in such deployment scenario, we leave the field empty:<\/p>\n<p><a title=\"ro-dc_10.png\" href=\"http:\/\/steverosa.files.wordpress.com\/2007\/07\/ro-dc_10.png\"><img decoding=\"async\" src=\"http:\/\/steverosa.files.wordpress.com\/2007\/07\/ro-dc_10.png?w=595\" alt=\"ro-dc_10.png\" \/><\/a><\/p>\n<p>The next step is about specifying the folders for the AD database, the log files and the SYStem VOLume:<\/p>\n<p><a title=\"ro-dc_11.png\" href=\"http:\/\/steverosa.files.wordpress.com\/2007\/07\/ro-dc_11.png\"><img decoding=\"async\" src=\"http:\/\/steverosa.files.wordpress.com\/2007\/07\/ro-dc_11.png?w=595\" alt=\"ro-dc_11.png\" \/><\/a><\/p>\n<p>Then, we specify the Directory Services Restore Mode (DSRM) password for the Domain Controller:<\/p>\n<p><a title=\"ro-dc_12.png\" href=\"http:\/\/steverosa.files.wordpress.com\/2007\/07\/ro-dc_12.png\"><img decoding=\"async\" src=\"http:\/\/steverosa.files.wordpress.com\/2007\/07\/ro-dc_12.png?w=595\" alt=\"ro-dc_12.png\" \/><\/a><\/p>\n<p>The wizard offers to review all the options selected and even  provides a way to export the settings to an answer file for future  re-use:<\/p>\n<p><a title=\"ro-dc_13.png\" href=\"http:\/\/steverosa.files.wordpress.com\/2007\/07\/ro-dc_13.png\"><img decoding=\"async\" src=\"http:\/\/steverosa.files.wordpress.com\/2007\/07\/ro-dc_13.png?w=595\" alt=\"ro-dc_13.png\" \/><\/a><\/p>\n<p>Finally, the actual installation and replication process starts.
