When you install the Administration Tools Pack on a computer that is running Windows XP Professional x64 Edition, the Active Directory Users and Computers MMC snap-in file (Dsa.msc) is installed in the %windir%\Syswow64 folder. Additionally, the computer's file system maps the Active Directory Users and Computers MMC snap-in to the following path: DriveLetter:\%windir%\Syswow64\Dsa.mscHowever, the Active Directory Domains and Trust MMC snap-in incorrectly specifies the path of the Active Directory Users and Computers MMC snap-in as follows: DriveLetter:\%windir%\System32\Dsa.mscWhen the computer's file system tries to locate the Dsa.msc file from within the Active Directory Domains and Trust MMC snap-in, Mmc.exe is run. Mmc.exe is run because the Dsa.msc file is associated with Mmc.exe. When Mmc.exe is run, it uses the following path to locate Dsa.msc: DriveLetter:\%windir%\System32\Dsa.msc DomainPathAfter the Mmc.exe command is run, the Active Directory Domains and Trust MMC snap-in tries to locate the Dsa.msc file. Because the Dsa.msc file does not exist in the %windir%\System32 folder, the error message that is mentioned in the "Symptoms" section is generated.

To resolve this problem, manually copy the Dsa.msc file from the %windir%\Syswow64 folder to the %windir%\System32 folder.

Your hardware manufacturer provides technical support and assistance for Microsoft Windows x64 editions. Your hardware manufacturer provides support because a Windows x64 edition was included with your hardware. Your hardware manufacturer might have customized the Windows x64 edition installation with unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with your Windows x64 edition. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware.

there is no backup for Active Directory only. you can backup the PDC or the BDC as a whole. or to backup the system state data.

Active Directory is same as registry. backup the AD will help you any when the machine goes down. you don't have the link to all of the services.

Plenty of information here.

Hello,

You have not mentioned the Operating system you are using. I am giving you a solution assuming that you are using Win XP.

There are two ways to fix this issue.
1. You need to extract this file from the CD and than copy into the root directory.
2. You can run a repair of the Win XP using the disk.

The second option is the better and the easy one. I have provided the link below where you have step by step instructions for the same with screen shots.

How to Repair Win XP

Hope this helps.

Active Directory (AD) is a technology created by Microsoft that provides a variety of network services, including:

• LDAP-like[1][2] directory services
• Kerberos based authentication
• DNS based naming and other network information

using the same database, for use primarily in Windows environments. Active Directory also allows administrators to assign policies, deploy software, and apply critical updates to an organization. Active Directory stores information and settings in a central database. Active Directory networks can vary from a small installation with a few hundred objects, to a large installation with millions of objects (though not easily [3]).
Active Directory was previewed in 1996, released first with Windows 2000 Server edition, and revised to extend functionality and improve administration in Windows Server 2003. Additional improvements were made in both Windows Server 2003 R2 and Windows Server 2008.
Active Directory was called NTDS (NT Directory Service) in older Microsoft documents. This name can still be seen in some AD binaries.
There is a common misconception that Active Directory provides software distribution. Software distribution is run by a separate service that uses additional proprietary schema attributes that work in conjunction with the LDAP protocol. Active Directory does not automate software distribution, but provides a mechanism by which other services can provide software distribution.

Basically because network file access to files on local networks (or geographically convienent locations) can speed access and or distribute network load this feature supports the creation and maintenence of multiple copies of data to facilitate timely access for a geographically distributed set of users. Depending on the size and user requirements this could be as close as replication between two buildings for higher volume use or as far as Europe or Asia for lower volumes of use to minimize internet traffic on could be relatively narrow and costly communication links between the continents.
