Test-ADDSDomainInstallation

Runs the prerequisites (only) for installing a new Active Directory domain configuration.

Syntax

Parameter Set: ADDSDomain
Test-ADDSDomainInstallation -NewDomainName <String> -ParentDomainName <String> [-ADPrepCredential <PSCredential> ] [-AllowDomainReinstall] [-CreateDnsDelegation] [-Credential <PSCredential> ] [-DatabasePath <String> ] [-DnsDelegationCredential <PSCredential> ] [-DomainMode <DomainMode> ] [-DomainType <DomainType> ] [-Force] [-InstallDns] [-LogPath <String> ] [-NewDomainNetbiosName <String> ] [-NoDnsOnNetwork] [-NoGlobalCatalog] [-NoRebootOnCompletion] [-ReplicationSourceDC <String> ] [-SafeModeAdministratorPassword <SecureString> ] [-SiteName <String> ] [-SkipAutoConfigureDns] [-SysvolPath <String> ] [ <CommonParameters>]




Detailed Description

The Test-ADDSDomainInstallation cmdlet runs those prerequisite checks (only) which would be performed if you were to use the Install-ADDSDomain cmdlet to install a new Active Directory domain configuration. It differs from using the -WhatIf parameter with the Install-ADDSDomain cmdlet in that instead of summarizing the changes that would occur during the installation process, this cmdlet actually tests whether those changes are possible given the current environment.

For more information on the scope of these prerequisite checks that the ADDSDeployment module performs when using this cmdlet see the section "Prerequisite Checking" in Understand and Troubleshoot AD DS Simplified Administration.

Parameters

-ADPrepCredential<PSCredential>

Specifies the user name and password that corresponds to the account to be used for running operations (if they are required) to prepare Active Directory prior to the installation of this domain. Specify "(Get-Credential)" to prompt the user to supply a password.

-DomainMode<DomainMode>

Specifies the domain functional level of the first domain in the creation of a new forest. Supported values for this parameter can be either a valid integer or a corresponding enumerated string value. For example, to set the domain mode level to Windows Server 2008 R2, you can specify either a value of 4 or Win2008R2.

The following are the supported values:

     -- Windows Server 2003: 2 or Win2003
     -- Windows Server 2008: 3 or Win2008
     -- Windows Server 2008 R2: 4 or Win2008R2
     -- Windows Server 2012: 5 or Win2012
     -- Windows Server 2012 R2: 6 or Win2012R2

The domain functional level cannot be lower than the forest functional level, but it can be higher. The default is automatically computed and set.

-DomainType<DomainType>

Indicates the type of domain that you want to create: a new domain tree in an existing forest (supported values are "TreeDomain" or "tree"), a child of an existing domain (supported values are "ChildDomain" or "child"). The default is ChildDomain.

-InstallDns

Specifies whether the DNS Server service should be installed and configured for the domain or domain tree. For domain installation, if this parameter is left unspecified and the parent domain (or in the case of a domain tree, the forest root domain) already hosts and stores the DNS names for the domain, then the default for this parameter is $true and the DNS server will be installed. Otherwise, if DNS domain names are hosted outside of Active Directory, the default is $false and no DNS server will be installed.

To test if DNS domain names are hosted outside of Active Directory, this cmdlet uses a start of authority (SOA) type DNS query to ask the question "Does a zone exist for the domain name?" For example, if the value of -NewDomainName is "corp.contoso.com", Active Directory performs an SOA query for "corp.contoso.com" and ensures that the zone name in the response is " corp.contoso.com".

-NewDomainName<String>

If the value set for -DomainType is set to "TreeDomain", this parameter can be used to specify the fully qualified domain name (FQDN) for the new domain tree (for example, "contoso.com"). If the value set for -DomainType is set to "ChildDomain", this parameter can be used to specify a single label domain name for the child domain (for example, specify "corp" to make a new doman "corp.contoso.com" if the new domain is in the contoso.com domain tree).

-NewDomainNetbiosName<String>

Specifies the NetBIOS name for the new domain. For NetBIOS names to be valid for use with this parameter they must be single label names of 15 characters or less.

If this parameter is set with a valid NetBIOS name value, then promotion continues with the name specified. If this parameter is not set, then the default is automatically computed from the value of the -NewDomainName parameter.

For example, if this parameter is not specified and a single-label prefix domain name of 15 characters or less is specified within the value of the -NewDomainName parameter, then promotion continues with an automatically generated NetBIOS domain name. For example, the prefix label "corp" within a full domain name value of "corp.contoso.com" would be a successful name choice.

Note that if the name value given for this parameter (or if it is omitted, the value of the single-label prefix domain name within the -NewDomainName parameter) is a name of 16 characters or more, then the domain installation fails. For example, if a value of "CORPORATEHEADQTRS" were specified for this parameter (or if this parameter is omitted and the value of -NewDomainName were set to be "corporateheadqtrs.contoso.com") then the domain installation will fail.

-NoDnsOnNetwork

Specifies that DNS service is not available on the network. This parameter is used only when the IP setting of the network adapter for this computer is not configured with the name of a DNS server for name resolution. It indicates that a DNS server will be installed on this computer for name resolution. Otherwise, the IP settings of the network adapter must first be configured with the address of a DNS server.

Omitting this parameter (the default) indicates that the TCP/IP client settings of the network adapter on this server computer will be used to contact a DNS server. Therefore, if you are not specifying this parameter, ensure that TCP/IP client settings are first configured with a preferred DNS server address.

-NoRebootOnCompletion

Specifies whether to restart the computer upon completion, regardless of success. (By default, reboot upon completion occurs when this cmdlet is used and this parameter is omitted.) As a general rule, Microsoft support recommends that you not use this parameter except for testing or troubleshooting purposes because once configuration has completed the server will not function correctly as either a member server or a DC until it is rebooted.

-SafeModeAdministratorPassword<SecureString>

Supplies the password for the administrator account when the computer is started in Safe Mode or a variant of Safe Mode, such as Directory Services Restore Mode. You must supply a password that meets the password complexity rules of the domain and the password cannot be blank. If specified with a value, the value must be a secure string.

If this parameter is not specified, the cmdlet prompts you to enter and confirm a masked password. This is the preferred usage when running the cmdlet interactively. If additionally there are no other arguments specified with the cmdlet, you will be prompted to enter a masked password for this parameter but no confirmation of the password entered will be made (which is not recommended as it could allow a mistyped password to be configured). Another available advanced option is to use the ConvertTo-SecureString cmdlet and specify the password string inline as unmasked console input, which is also not a recommended security best practice in production deployments.

Examples

-------------------------- EXAMPLE 1 --------------------------

Description

-----------

Runs the prerequisites (only) to determine if installing a new child domain named child.corp.contoso.com using credentials of CORP\EnterpriseAdmin1 is possible. This example also installs a DNS server, creates a DNS delegation in the corp.contoso.com domain, sets the domain functional level to Windows Server 2003, makes the domain controller a global catalog server in a site named Houston, uses DC1.corp.contoso.com as the replication source domain controller, installs the Active Directory database and SYSVOL on the D:\ drive, installs the log files on the E:\ drive, has the server not automatically restart after the domain installation is complete and causes the user to be prompted to provide and confirm the Directory Services Restore Mode (DSRM) password to complete and commit the installation of the domain in Active Directory.


PS C:\> Test-ADDSDomainInstallation -Credential (Get-Credential CORP\EnterpriseAdmin1) -NewDomainName child -ParentDomainName corp.contoso.com -InstallDNS -CreateDNSDelegation -DomainMode Win2003 -ReplicationSourceDC DC1.corp.contoso.com -SiteName Houston -DatabasePath "D:\NTDS" -SYSVOLPath "D:\SYSVOL" -LogPath "E:\Logs" -NoRebootOnCompletion
