The Active Directory database mounting tool (Dsamain.exe) can improve recovery
processes for your organization by providing a means to compare data as it exists in
snapshots that are taken at different times so that you can better decide which data to
restore after data loss. This eliminates the need to restore multiple backups to compare the
Active Directory data that they contain.
Requirements for using the Active Directory database mounting tool
You do not need any additional software to use the Active Directory database mounting tool.
All the tools that are required to use this feature are built into Windows Server 2008 and are
available if you have the AD DS or the AD LDS server role installed. These tools include the
following:
Dsamain.exe, which you can use to expose the snapshot data as an LDAP server
Existing LDAP tools, such as Ldp.exe and Active Directory Users and Computers
