How to Perform Authoritative DC Restore for Windows Server 2008

Video Tutorials, Windows Server
When a domain contains more than one domain controller, Active Directory replicates directory objects, such as users, groups, organizational units, and computers, to all the domain controllers in that domain. Authoritative restore is a method to recover objects and containers that have been deleted for AD DS. An authoritative restore marks specific data as current and prevents the replication from overwriting that data. The authoritative data is then replicated throughout the domain. The process for performing an authoritative restore of AD is the same as a Non-authoritative restore except for one step. After the restore of AD is complete in DSRM and then, before restarting, you manually run Ntdsutil, and the mark the object that you want to restore as Authoritative.

VMware, Windows Server
Be sure the virtual machine has at least 2GB of RAM. Hard drive for the virtual machine must be 20GB or larger.

How to Perform Step by Step Exchange 2010 Single Mailbox Item Restore with Windows Server Backup

Exchange Server, Video Tutorials
Exchange Server 2010 no longer has the notion of Storage Groups, which were used in Exchange 2007 and 2003 to contain logical groupings of databases. Exchange 2010 now simply lets you create databases on mailbox servers. The difference is that in Exchange 2003/2007, you created a Recover Storage Group (RSG) to restore the database into. In Exchange 2010, you simply restore the database and connect to it as a Recovery Database (RDB). While the main purpose of Exchange backup is to enable server, storage, and datacenter disaster recovery scenarios, a common and routine request of Exchange admins is to restore an individual mailbox. Microsoft does not provide a native and fully automated way to granularly restore a single mailbox from an Exchange database backup. In this video I'll demonstrate the…
