After you install DHCP servers in the new domain or domain tree, you can assign the domain controller a dynamic IP address. Creating an additional domain controller in an existing domain: If you are creating an additional domain controller in an existing domain, you should consider whether you want to perform an installation from media rather than creating the domain controller from scratch.
With either technique, you need to log on to the local machine using either the local Administrator account or an account that has administrator privileges on the local machine, and then start the installation. You will also be required to provide the credentials for an account that is a member of the Domain Admins group in the domain of which the domain controller will be a part. Because you are installing an additional domain controller, the server should already be a member of the domain and must have a valid IP address.
This means the server must have an appropriate IP address, as discussed previously. It also might mean that the server needs to have an appropriate subnet mask and default gateway, as well as preferred and alternate DNS server settings. If the wizard displays the Before You Begin page, read the Welcome message and then tap or click Next. On the Select Destination Server page, the server pool shows servers you added for management. Tap or click the server you are configuring, and then tap or click Next.
If the computer is currently a member server, the wizard takes you through the steps needed to install Active Directory Domain Services, which might include running Adprep.
Upgrading the forest requires credentials that include group memberships in Enterprise Admins, Schema Admins and Domain Admins for the forest root domain. Upgrading a domain, other than the forest root domain, requires credentials that include group memberships in Domain Admins. You must run Adprep. You need to prepare Group Policy only once, not for every upgrade. Group Policy isn't automatically prepared because these preparations can cause all files and folders in the SYSVOL folder to re-replicate on all domain controllers.
Creating additional domain controllers for an existing domain To create an additional domain controller for an existing domain, follow these steps: Start the Active Directory Domain Services Configuration Wizard as discussed previously. Remember: Note the verification error. You can see this same verification error for several other reasons as well: if you type an invalid domain name, or if all the domain controllers in the specified domain are offline.
You need to correct the issue before you can continue. A verification error also occurs if you enter the wrong password when setting credentials. Here, the error states: "Verification of replica failed. The wizard cannot access the list of domains in the forest. The user name or password is incorrect. In the Domain box, type the full DNS name of the domain in the forest where you plan to install the domain controller, such as cpandl.
To select a domain in the forest from a list of available domains, tap or click Select. If you are logged on to a domain in this forest and have the appropriate permissions, you can use your current logged-on credentials to perform the installation. Otherwise, you need to provide alternate credentials.
Tap or click Change. In the Windows Security dialog box, type the user name and password for an enterprise administrator account in the previously specified domain and then tap or click OK. When you tap or click Next, the wizard performs several preliminary checks and then displays the Domain Controller Options page. The wizard does the following: Checks any user credentials you entered to ensure that the user name and password are valid. The wizard doesn't verify user credential permissions until the Prerequisite Checks, which occur just before installation.
Determines the available Active Directory sites. The most appropriate site for the server's current subnet is selected by default on the Domain Controller Options page. As permitted, select additional installation options. The domain controller can be a DNS server, global catalog server, or both.
To ensure high availability of directory services, all domain controllers should provide DNS and global catalog services. Global Catalog is always selected by default. Select the Active Directory site in which you want to locate the domain controller. By default, the wizard selects the site with the most correct subnet.
If there is only one site, the wizard selects that site automatically. No automatic selection is made if the server does not belong to an Active Directory subnet and there are multiple sites available. Type and confirm the password that should be used when you want to start the computer in Directory Services Restore Mode.
Be sure to track this password carefully. This special password is used only in Restore mode and is different from the Administrator account password. It is the local Administrator password, which is in the local database of domain controllers; this database normally is hidden.
To continue, tap or click Next. The next page you see depends on whether you are installing DNS Server. If you are installing the DNS Server service as an additional option, the wizard next attempts to register a delegation for the DNS server with an authoritative parent zone. If you are integrating with an existing DNS infrastructure, you should manually create a delegation to the DNS server. Otherwise, you can ignore this warning. Tap or click Next to continue. Note: Before continuing, make sure you check for encrypted files and folders as discussed in the section Active Directory installation options and issues earlier in this tutorial.
If you don't do this and there are encrypted files and folders present, you will only be able to decrypt them using previously backed-up recovery agent EFS private keys. If you don't have backups of these keys, you won't be able to decrypt previously encrypted files and folders.
On the Additional Options page, specify whether to replicate the necessary Active Directory data from media or over the network. When you are installing from media, you must specify the folder location of the media before continuing. Saved Queries in ADUC allows administrators to access and audit information in AD and filter just those objects that meet a certain criteria.

Some of the tasks an administrator can perform with the help of this MMC snap-in are as follows: Create and manage AD objects, such as users, computers, groups, and contacts, along with their attributes. Delegate permissions to users to manage Group Policy. Define advanced security and auditing in AD. Raise the domain functional level. Click on Manage Optional Features. Unfortunately it doesn't work even with SMB1 enabled on the Server After some research I suspect that this Kerberos issue with RC4 encryption protocol.
Saturday, December 22, PM. I think ,it's time to migrate to other version. Now XP it's not supported by Microsoft. To avoid any compatibility issue with new OS, yu should to migrate it soon as possible. Sunday, January 13, AM. Monday, January 14, PM. Tuesday, January 15, PM. Same issue here, is there any solution for this? Monday, February 25, AM. Can't join any old client that needs supporting the RC4 encryption protocol for kerberos tgt.
Are you sure that you succeeded to join XP SP3? Neither SP3 or without SP3. Monday, February 25, PM. Tuesday, February 26, AM. Its totaly anoying, i cannot find any differences It's very interesting. Can you check this and provide us with results, please? Tuesday, February 26, PM. I will check it as soon as possible. Credential requirements to run Adprep. To install a new child domain or new domain tree, you must be logged on as a member of the Enterprise Admins group.
To install an additional domain controller in an existing domain, you must be a member of the Domain Admins group. If you do not run adprep. The credential requirements are as follows:. To introduce the first Windows Server domain controller in the forest, you need to supply credentials for a member of Enterprise Admins group, the Schema Admins group, and the Domain Admins group in the domain that hosts the schema master.
To introduce the first Windows Server domain controller in a domain, you need to supply credentials for a member of the Domain Admins group. To introduce the first read-only domain controller RODC in the forest, you need to supply credentials for a member of the Enterprise Admins group. The ability to continue running dcpromo.
For more information about running dcpromo. Start with adding the role using Windows PowerShell. Server administration tools are not installed by default when you use Windows PowerShell. You need to specify "IncludeManagementTools to manage the local server or install Remote Server Administration Tools to manage a remote server. For example, to see the arguments for creating an unoccupied read-only domain controller RODC account, type.
You can also download the latest Help examples and concepts for Windows PowerShell cmdlets. ADDSDeployment cmdlet arguments. Specifying Windows PowerShell Credentials. Using test cmdlets. Installing a new forest root domain using Windows PowerShell.
Installing a new child or tree domain using Windows PowerShell. Installing an additional replica domain controller using Windows PowerShell. Arguments in bold are required. Equivalent arguments for dcpromo. For example, because -installdns is automatically run for a new forest installation if it is not specified, the only way to prevent DNS installation when you install a new forest is to use:. If no value is specified, the value of the "credential argument is used.
AllowDomainControllerReinstall Specifies whether to continue installing this writable domain controller, despite the fact that another writable domain controller account with the same name is detected. This argument is not valid for an RODC.
AllowDomainReinstall Specifies whether an existing domain is recreated. Use an empty string "" if you want to keep the value empty. Supply values as a string array. Specifies the application directory partitions to replicate. By default, all application partitions will replicate based on their own scopes.
For example: Code - -ApplicationPartitionsToReplicate "partition1","partition2","partition3" Confirm Prompts you for confirmation before running the cmdlet. Indicates whether to create a DNS delegation that references the new DNS server that you are installing along with the domain controller. Delegation records can be created only on Microsoft DNS servers that are online and accessible.
Delegation records cannot be created for domains that are immediately subordinate to top-level domains such as. The default is computed automatically based on the environment. Specifies the domain account that can logon to the domain, according to the rules of Get-Credential and a PSCredential object. If no value is specified, the credentials of the current user are used. CriticalReplicationOnly Specifies whether the AD DS installation operation performs only critical replication before reboot and then continues.
The noncritical replication happens after the installation finishes and the computer reboots. Using this argument is not recommended. There is no equivalent for this option in the user interface UI. Use an empty string "" if you do not want to deny the replication of credentials of any users or computers.
The domain functional level cannot be lower than the forest functional level, but it can be higher. The default value is automatically computed and set to the existing forest functional level or the value that is set for -ForestMode. Specifies the FQDN of the domain in which you want to install an additional domain controller. The default for DomainType is ChildDomain. Force When this parameter is specified any warnings that might normally appear during the installation and addition of the domain controller will be suppressed to allow the cmdlet to complete its execution.
This parameter can be useful to include when scripting installation. The default value is Win InstallationMediaPath Indicates the location of the installation media that will be used to install a new domain controller.
MoveInfrastructureOperationMasterRoleIfNecessary Specifies whether to transfer the infrastructure master operations master role also known as flexible single master operations or FSMO to the domain controller that you are creating"in case it is currently hosted on a global catalog server"and you do not plan to make the domain controller that you are creating a global catalog server.
Specify this parameter to transfer the infrastructure master role to the domain controller that you are creating in case the transfer is needed; in this case, specify the NoGlobalCatalog option if you want the infrastructure master role to remain where it currently is. Specifies the single domain name for the new domain.
For example, if you want to create a new child domain named emea.
