Detailed Description

The Test-ADDSDomainControllerInstallation cmdlet runs those prerequisite checks (only) which would be performed if you were to use the Install-ADDSDomainController cmdlet to install a domain controller in Active Directory. It differs from using the -WhatIf parameter with the Install-ADDSDomainController 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.

-CriticalReplicationOnly

Specifies whether the AD DS installation operation performs only critical replication before reboot and then continues, skipping the noncritical (and potentially lengthy) portion of replication.

By default, Administrators, Server Operators, Backup Operators, Account Operators, and the Denied RODC Password Replication Group are denied. By default, the Denied RODC Password Replication Group includes Cert Publishers, Domain Admins, Enterprise Admins, Enterprise Domain Controllers, Enterprise Read-Only Domain Controllers, Group Policy Creator Owners, the krbtgt account, and Schema Admins.

-InstallDns

Specifies whether the DNS Server service should be installed and configured on the domain controller. For domain controller installation, if this parameter is left unspecified and the current 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 -DomainName 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".

-MoveInfrastructureOperationMasterRoleIfNecessary

Use 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, make sure not to use the -NoGlobalCatalog switch parameter as well. Do not specify this parameter if you want the infrastructure master role to remain where it currently is.

-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

If specified, the computer will not restart upon the completion of the operation to install the domain controller. By default, if this parameter is omitted the computer will restart upon the completion of the install operation. 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. If no value is specified for this parameter, the cmdlet prompts you to enter and confirm a masked password. If specified with a value, the value must be a secure string.

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.

-SiteName<String>

Specifies the name of an existing site where you can place the new domain controller. The default value depends on the type of installation. For a new forest, the default is Default-First-Site-Name. For all other installations, the default is the site that is associated with the subnet that includes the IP address of this server. If no such site exists, the default is the site of the replication source domain controller.

Examples

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

Description

-----------

Runs the prerequisites (only) to determine if installing a domain controller is possible that includes a DNS server for the corp.contoso.com domain (using domain administrator credentials) and that will cause the user to be prompted to enter and confirm the Directory Services Restore Mode (DSRM) password.

-------------------------- EXAMPLE 2 --------------------------

Description

-----------

C:\PS>Test-ADDSDomainControllerInstallation -InstallDns -DomainName "corp.contoso.com "

-------------------------- EXAMPLE 3 --------------------------

Description

-----------
