What will happen if you install a DHCP server on a network without Active Directory?
Without Active Directory the DHCP server cannot be authorized, and could therefore be considered a "rogue". What A.D do for a DHCP Server that it authorised to DHCP server to give an Ip add. to clients and authorised for update the DNS PTR records. and when we won't authorised DHCP with Active Directory it won't be update the the PTR records and won't be update the IP add. in DNS records.
What dns solution supports secure dynamic dns?
Active Directory-Integrated DNS Active Directory-integrated DNS enables Active Directory storage and replication of DNS zone databases. Windows 2000 DNS server, the DNS server that is included with Windows 2000 Server, accommodates storing zone data in Active Directory. When you configure a computer as a DNS server, zones are usually stored as text files on name servers - that is, all of the zones required by DNS are stored in a text file on the server computer. These text files must be synchronized among DNS name servers by using a system that requires a separate replication topology and schedule called a zone transfer However, if you use Active Directory-integrated DNS when you configure a domain controller as a DNS name server, zone data is stored as an Active Directory object and is replicated as part of domain replication. note-icon Note Only DNS servers that run on domain controllers can load Active Directory-integrated zones. To use DNS integration within Active Directory, assign the zone type Active Directory-integrated when you create the zone.Objects that represent zone database records are created in the Microsoft DNS container within the System container (visible in the Advanced Features view in Active Directory Users and Computers), and the contents are replicated to all domain controllers in the domain. When you have Active Directory-integrated DNS zones, all Active Directory domain controllers that run Windows 2000 DNS server and are appropriately configured function as primary name servers. When DNS data is stored in Active Directory, each DNS zone is an Active Directory container object (class dnsZone ). The dnsZone object contains a DNS node object (class dnsNode ) for every unique name within that zone. These unique names include the variations assigned to a specific host computer when it functions, for example, as a primary domain controller or as a Global Catalog server. The dnsNode object has a dnsRecord multivalue attribute that contains a value for every resource record that is associated with an object's name. When other non-Windows 2000 DNS servers are already in place and Active Directory domains represent only part of the overall DNS namespace, standard zone transfer still can be used to synchronize zone data between Active Directory and other DNS servers When Windows 2000 DNS server is installed on at least one domain controller and has Active Directory-integrated zones, the zone data is always replicated to every domain controller in the domain. How DNS integrates with Active Directory When you install Active Directory on a server, you promote the server to the role of a domain controller for a specified domain. When completing this process, you are prompted to specify a DNS domain name for the Active Directory domain for which you are joining and promoting the server. If during this process, a DNS server authoritative for the domain that you specified either cannot be located on the network or does not support the DNS dynamic update protocol, you are prompted with the option to install a DNS server. This option is provided because a DNS server is required to locate this server or other domain controllers for members of an Active Directory domain. Once you have installed Active Directory, you have two options for storing and replicating your zones when operating the DNS server at the new domain controller: * Standard zone storage, using a text-based file. Zones stored this way are located in .Dns files that are stored in the systemroot\System32\Dns folder on each computer operating a DNS server. Zone file names correspond to the name you choose for the zone when creating it, such as abc.com.dns if the zone name was "abc.com." * Directory-integrated zone storage, using the Active Directory database. Zones stored this way are located in the Active Directory tree under the domain or application directory partition. Each directory-integrated zone is stored in a dnsZone container object identified by the name you choose for the zone when creating it. Benefits of Active Directory integration For networks deploying DNS to support Active Directory, directory-integrated primary zones are strongly recommended and provide the following benefits: * Multimaster update and enhanced security based on the capabilities of Active Directory. In a standard zone storage model, DNS updates are conducted based upon a single-master update model. In this model, a single authoritative DNS server for a zone is designated as the primary source for the zone. This server maintains the master copy of the zone in a local file. With this model, the primary server for the zone represents a single fixed point of failure. If this server is not available, update requests from DNS clients are not processed for the zone. With directory-integrated storage, dynamic updates to DNS are conducted based upon a multimaster update model. In this model, any authoritative DNS server, such as a domain controller running a DNS server, is designated as a primary source for the zone. Because the master copy of the zone is maintained in the Active Directory database, which is fully replicated to all domain controllers, the zone can be updated by the DNS servers operating at any domain controller for the domain. With the multimaster update model of Active Directory, any of the primary servers for the directory-integrated zone can process requests from DNS clients to update the zone as long as a domain controller is available and reachable on the network. Also, when using directory-integrated zones, you can use access control list (ACL) editing to secure a dnsZone object container in the directory tree. This feature provides granulated access to either the zone or a specified RR in the zone. For example, an ACL for a zone RR can be restricted so that dynamic updates are only allowed for a specified client computer or a secure group such as a domain administrators group. This security feature is not available with standard primary zones. Note that when you change the zone type to be directory-integrated, the default for updating the zone changes to allow only secure updates. Also, while you may use ACLs on DNS-related Active Directory objects, ACLs may only be applied to the DNS client service. * Zones are replicated and synchronized to new domain controllers automatically whenever a new one is added to an Active Directory domain. Although DNS service can be selectively removed from a domain controller, directory-integrated zones are already stored at each domain controller, so zone storage and management is not an additional resource. Also, the methods used to synchronize directory-stored information offer performance improvement over standard zone update methods, which can potentially require transfer of the entire zone. * By integrating storage of your DNS zone databases in Active Directory, you can streamline database replication planning for your network. When your DNS namespace and Active Directory domains are stored and replicated separately, you need to plan and potentially administer each separately. For example, when using standard DNS zone storage and Active Directory together, you would need to design, implement, test, and maintain two different database replication topologies. For example, one replication topology is needed for replicating directory data between domain controllers, and another topology would be needed for replicating zone databases between DNS servers. This can create additional administrative complexity for planning and designing your network and allowing for its eventual growth. By integrating DNS storage, you unify storage management and replication issues for both DNS and Active Directory, merging and viewing them together as a single administrative entity. * Directory replication is faster and more efficient than standard DNS replication. Because Active Directory replication processing is performed on a per-property basis, only relevant changes are propagated. This allows less data to be used and submitted in updates for directory-stored zones.
Which dns solution supports secure dynamic dns?
The Active directory integrated zone helps to to secure dns and gives dynamic updates of DNS in the domain.

Why is dns a requirement for active directory to work?
DNS is extremely important to all aspects of proper Active Directory operation. Any time a client makes a request for a domain service, it must find a domain controller to service that request, which is where DNS comes in to play.There are two types of DNS queries: recursive and iterative.When a DNS client requests DNS information, it uses a recursive query to do so.In a recursive query, the DNS client sends its query to the first DNS server that it has been configured for in its TCP/IP configuration. It then sits and waits for the server to return an answer. If the server returns a positive response, the client will then go to the IP address returned by the server.
What can be used to add delete or modify objects in Active Directory in addition to modifying the schema if necessary?
LDIFDE is a robust utility. This utility enabled you to import/export information from/to Active Directory. LDIFDE queries any available domain controller to retrieve/update AD information. Ldifde creates, modifies, and deletes directory objects on computers running Windows Server 2003 operating systems or Windows XP Professional. You can also use Ldifde to extend the schema, export Active Directory user and group information to other applications or services, and populate Active Directory with data from other directory services
Is it possible to restore active directory windows 2003 to windows 2008 server?
No, you cannot restore AD from 2003 to 2008 directly. You need to upgrade the AD infrastructure to 2008 (schema update).
What is the role of active directory edirectory and open directory?
Active Directory will represent a major advance over NT 4.0's simple domain model, since the domains within Active Directory will be able to form a multi-level tree structure.Users will be able to establish two-way transitive trust relationships among these domains. Lower-level domains trust all the higher-level domains within the hierarchical tree. This arrangement will make trust relationships easier to manage and will make possible the delegation of administrative authority from higher to lower levels within the tree.Active Directory will bear on security in two ways.First, Active Directory will be the repository for security policy information for the enterprise. For example, Active Directory will be able to store domain-wide password restrictions and system access privileges.Second, Active Directory will incorporate the object-based security model, controlling each user or group's right to read or update objects within the directory. The directory will therefore be able to hold such important items as encrypted passwords and user certificates with the assurance that only authorized users will be able to read or change them.

How do you update Minecraft to 1.5?
When an update is released Minecraft will ask you if you want to update as it starts.You can update Minecraft manually by downloading the version, weekly update or pr-release you want as minecraft.jar, and replacing the minecraft.jar in the bin folder of the Minecraft directory
Which directory partition contains all objects in a domain?
Contains a < domain > container (for example, the abc.com container), which stores users, computers, groups, and other objects for a specific Windows domain (for example, the abc.com domain). Updates to the < domain > container are replicated to only domain controllers within the domain and to Global Catalog servers if the update is made to an attribute that is marked for replication to the Global Catalog. The < domain > container is displayed in the Active Directory Users and Computers console. The hierarchy of domain directory partitions can be viewed in the Active Directory Domains and Trusts console, where trust relationships between domains can be managed.
