A Microsoft Windows Active Directory Domain is a directory service for a computer network. Think of it like a phonebook for all your companies computers, users, and printers to name a few. Active Directory provides a central authentication point for all users/computers in the building and controls network policies. This makes network management for multiple computers and users MUCH easier.
If active Directory is not in administrative tools then it is likely that the machine is not configrued as a domain controller. You will need to add this as a role through server manager. Once configured as a domain controller Active Directory will appear under admin tools
DNS is the primary name resolution service for Windows Server 2003. Active Directory depends on DNS for domain controller location, and DNS influences Active Directory domain naming. Thus, to fully understand Active Directory, it helps to understand how DNS acts as an integral component in the design of Active Directory.
DNS provides Active Directory with both a name resolution service for domain controller location and a hierarchical design that Active Directory leverages to provide a naming convention that can reflect organizational structure.
Typically, a DNS domain namespace deployed to accommodate the Active Directory mirrors the Active Directory domain namespace. In cases where there is an existing DNS namespace prior to Active Directory deployment, the DNS namespace is typically partitioned for Active Directory, and a DNS subdomain and delegation for the Active Directory forest root is created. Additional DNS domain names are then added for each Active Directory child domain.
DNS data is used to support the location of Active Directory domain controllers also. During or after the creation of the DNS zones used to support Active Directory domains, the zones are populated with DNS resource records that enable network hosts and services to locate Active Directory domain controllers.
Active Directory think of it has management system for all network LAN PCs in your domain. You can add users to certain enterprise groups, you can disable accounts, push and pull software application better then you can in SMS domain. I use to to clone user accounts or create new user groups. Very easy to learn. To install on Server requires a domain, DNS. If you're using Windows Server 2003 and setup the server to manage active directory all the options for the installation process will appear for installation. There are a lot of info online and in books if you need more info. There are training classing offer at MS Solutions Centers.
Active Directory (AD) is a technology created by Microsoft that provides a variety of network services,
Active directory is a directory service used to store information about the network resources across a domain and also centralize the network.
DNS stands for Domain Name Server. These are the servers that match up a fully qualified domain with the proper IP address. This is necessary because computers only understand the IP address for your domain (eg- 123.45.678.90).
An application directory partition is represented by a domainDNS object with an instanceType attribute value of DS_INSTANCETYPE_IS_NC_HEAD combined with DS_INSTANCETYPE_NC_IS_WRITEABLE. This domainDNS object represents the application directory partition root (NC head), and is named similar to a regular domain partition, for example, "DC=dynamicdata,DC=fabrikam,DC=com", which corresponds to a DNS name of "dynamicdata.fabrikam.com". An application directory partition can, therefore, be instantiated anywhere a domain partition can be instantiated. There is no NetBIOS name associated with an application directory partition.
It is possible to nest application directory partitions, that is, an application directory partition can have child application directory partitions. Searches with subtree scope rooted at an application directory partition head will generate continuation references to the child application directory partitions.
An application directory partition replica can only be created on a domain controller that is running on Windows Server 2003 and later and only while the Domain-Naming FSMO role is held by a Windows Server 2003 and later domain controller. In a mixed forest that has both Windows Server 2003 domain controllers and down-level domain controllers (Windows 2000 domain controllers or Windows NT 4.0 primary domain controllers), an attempt to create an application directory partition replica on a down-level domain controller will fail.
An application directory partition also has a corresponding crossRef object in the Partitions container of the configuration partition. The crossRef can be pre-created manually before creating the domainDNS object. The pre-created crossRef object must have the attribute values shown in the following table or the partition creation will fail. If the crossRef object does not exist, the Active Directory server will create one when the application directory partition is created.
Make sure and keep copies of all the folders and files.
Take these actions to resolve your problem:
On all Active Directory registered domain controllers:
1. Stop NETLOGON Service
2. Stop File Replication Service (NTFRS)
On the PDC Emulator:
1. Rename all files in the %systemroot%\ntfrs folder and subfolders (change their extension to .old).
2. Give an unlisted account full control of the directory %systemroot%\SYSVOL folder and reset permissions on all child objects.
3. Change the registry key: HKLM\System\CurrentControlSet\Services\ntfrs\paramaters\Backup/Restore\Process at Startup\BurFlags (REG_DWORD) = D4 (The default on this is 0)
4. Start the NETLOGON Service
5. Start the NTFRS Service
On all non-PDC emulators:
1. Change the registry key: HKLM\System\CurrentControlSet\Services\ntfrs\paramaters\Backup/Restore\Process at Startup\BurFlags (REG_DWORD) = D2
2. Start the NETLOGON Service
3. Start the File Replication Service (NTFRS)
At this point, the system in question should have recreated the SYSVOL share and the NETLOGON share. Check this by running 'net share' from a command prompt. You should also see the Group Policy Objects listed in the SYSVOL directory as:
There may be more directories listed here, but these are the Default Domain Policy and the Default Domain Controllers Policy that are installed by default when the Active Directory is created. If these are being replicated, then file replication is functioning.
If you cannot find these directories, then you may have to manually recreate them. Here is a list of the proper directory structure of the %systemroot%\SYSVOL folder:
\SYSVOL ________\domain ________________\DO_NOT_REMOVE_NtFrs_PreInstall_Directory ________________\Policies ________________\Scripts ________\scripts ________\staging ________\staging areas ________________\domain_name ________\sysvol (shared as SYSVOL) ________________\domain_name ________________________\DO_NOT_REMOVE_NtFrs_PreInstall_Directory ________________________\Policies ________________________\Scripts (shared as NETLOGON)
If you have to manually recreate the directories, restart the File Replication Service (NTFRS) on all domain controllers to re-enable replication. This should get the file replication functioning normally
