Your network consists of a single Active Directory domain.
The domain contains a server that runs Windows Server 2008 R2.
The server has Microsoft SharePoint Foundation 2010 installed.

Explanation:
SharePoint Directory Management service
The SharePoint Directory Management service connects SharePoint sites to your organization’s user directory to provide enhanced e-mail features. The benefit of using this service is that it enables users to create and manage e-mail distribution groups from SharePoint sites. This service also creates contacts in your organization’s user directory so people can find e-mail-enabled SharePoint lists in their address books. However, using SharePoint Directory Management service requires more management because it is communicating with Active Directory Domain Services (AD DS).You can configure the SharePoint Directory Management service by using either the automatic or the advanced settings mode. You can choose to enable the SharePoint Directory Management service in your SharePoint server farm, or you can use the SharePoint Directory Management service of another farm. One advantage of using the service running on another farm is that Active Directory permissions are managed in a centralized place (that is, on the other farm).
To enable this service on a server or server farm runningSharePoint Foundation 2010, the SharePoint Central Administration application pool account used by SharePoint Foundation 2010 must have write access to the container that you specify in Active Directory. This requires an Active Directory administrator to set up the organizational unit (OU) and the permissions on the OU. The advantage of using the SharePoint Directory Management service on a remote farm is that you do not need the help of an Active Directory administrator to create and configure the OU if the OU already exists.
