Detailed Description

The New-ADReplicationSite cmdlet is used to create new sites in Active Directory replication. Sites are used in Active Directory to either enable clients to discover network resources (published shares, domain controllers) close to the physical location of a client computer or to reduce network traffic over wide area network (WAN) links. Sites can also be used to optimize replication between domain controllers.

Parameters

-AuthType<ADAuthType>

Specifies the authentication method to use. Possible values for this parameter include:

Negotiate or 0

Basic or 1

The default authentication method is Negotiate.

A Secure Sockets Layer (SSL) connection is required for the Basic authentication method.

The following example shows how to set this parameter to Basic.

-AuthType Basic

-AutomaticInterSiteTopologyGenerationEnabled<Boolean>

Prevents the KCC that functions as the intersite topology generator (ISTG) from generating connections for intersite replication. Use this option when you want to create manual intersite connections (disable the ISTG) but retain the KCC to generate intrasite connections.

-AutomaticTopologyGenerationEnabled<Boolean>

When enabled, prevents the KCC from generating intrasite connections on all servers in the site. Disable this option if you use manual connections and do not want the KCC to build connections automatically.

-Credential<PSCredential>

Specifies a user account that has permission to perform this action. The default is the current user.

Type a user name, such as "User01" or "Domain01\User01", or enter a PSCredential object, such as one generated by the Get-Credential cmdlet. If you type a user name, you will be prompted for a password.

This parameter is not supported by any providers installed with Windows PowerShell.

-Instance<ADReplicationSite>

Specifies an instance of a site object to use as a template for a new site object.

You can use an instance of an existing site object as a template or you can construct a new site object by using the Windows PowerShell command line or by using a script. The following examples show how to use these two methods to create a new site object.

Method 1: Use an existing site object as a template for a new object. To retrieve an instance of an existing site object, use the Get-ADReplicationSite cmdlet. Then provide this site object to the Instance parameter of the New-ADReplicationSite cmdlet to create a new site object. You can override property values of the new object by setting the appropriate parameters.

$objectInstance = Get-ADReplicationSite -Identity NorthAmerica

New-ADReplicationSite -Name "SouthAmerica" -Instance $ObjectInstance

Method 2: Create a new ADReplicationSite and set the property values by using the Windows PowerShell command line interface. Then pass this object to the Instance parameter of the New-ADReplicationSite cmdlet to create the new site object.

$objectInstance = new-object Microsoft.ActiveDirectory.Management.ADReplicationSite

$objectInstance.Description = "North America"

New-ADReplicationSite -Name "NorthAmerica" -Instance $ObjectInstance

Note: Specified attributes are not validated, so attempting to set attributes that do not exist or cannot be set will raise an error.

-ManagedBy<ADPrincipal>

Specifies the user or group that manages the object by providing one of the following property values. Note: The identifier in parentheses is the LDAP display name for the property.

Distinguished Name

Example: CN=SaraDavis,OU=Europe,CN=Users,DC=corp,DC=contoso,DC=com

GUID (objectGUID)

Example: 599c3d2e-f72d-4d20-8a88-030d99495f20

Security Identifier (objectSid)

Example: S-1-5-21-3165297888-301567370-576410423-1103

SAM Account Name (sAMAccountName)

Example: saradavis

This parameter sets the Active Directory attribute with an LDAP Display Name of "managedBy".

The following example shows how to specify this parameter.

-OtherAttributes<Hashtable>

Specifies object attribute values for attributes that are not represented by cmdlet parameters. You can set one or more parameters at the same time with this parameter. If an attribute takes more than one value, you can assign multiple values. To identify an attribute, specify the LDAPDisplayName (ldapDisplayName) defined for it in the Active Directory schema.

Syntax:

To specify a single value for an attribute:

-OtherAttributes @{'AttributeLDAPDisplayName'=value}

To specify multiple values for an attribute

-OtherAttributes @{'AttributeLDAPDisplayName'=value1,value2,...}

You can specify values for more than one attribute by using semicolons to separate attributes. The following syntax shows how to set values for multiple attributes:

-OtherAttributes @{'Attribute1LDAPDisplayName'=value; 'Attribute2LDAPDisplayName'=value1,value2;...}

The following examples show how to use this parameter.

To set the value of a custom attribute called favColors that takes a set of Unicode strings, use the following syntax:

-OtherAttributes @{'favColors'="pink","purple"}

To set values for favColors and dateOfBirth simultaneously, use the following syntax:

-OtherAttributes @{'favColors'="pink","purple"; 'dateOfBirth'=" 01/01/1960"}

-Server<String>

Specifies the Active Directory Domain Services instance to connect to, by providing one of the following values for a corresponding domain name or directory server. The service may be any of the following: Active Directory Lightweight Domain Services, Active Directory Domain Services or Active Directory Snapshot instance.

Domain name values:

Fully qualified domain name

Fully qualified directory server name

Example: corp-DC12.corp.contoso.com

NetBIOS name

Example: corp-DC12

Fully qualified directory server name and port

The default value for the Server parameter is determined by one of the following methods in the order that they are listed:

-By using Server value from objects passed through the pipeline.

-By using the server information associated with the Active Directory PowerShell provider drive, when running under that drive.

-By using the domain of the computer running Powershell.
