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.

Examples

C:\PS>New-ADReplicationSite NorthAmerica

Description


Create a new site named 'NorthAmerica'.

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

C:\PS>New-ADReplicationSite Europe -AutomaticInterSiteTopologyGenerationEnabled $FALSE

Description


Create a new site named 'Europe', and set the AutomaticInterSiteTopologyGenerationEnabled property on the new object.

Required Parameters

-Name

Specifies a name for the replication site object.

Type:String
Position:0
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False

Optional Parameters

-AuthType

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

Type:ADAuthType
Parameter Sets:Negotiate, Basic
Position:Named
Default value:Microsoft.ActiveDirectory.Management.AuthType.Negotiate
Accept pipeline input:False
Accept wildcard characters:False
-AutomaticInterSiteTopologyGenerationEnabled

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.

Type:Boolean
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-AutomaticTopologyGenerationEnabled

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.

Type:Boolean
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:False
Accept pipeline input:False
Accept wildcard characters:False
-Credential

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.

Type:PSCredential
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-Description

Specifies a description of the object. This parameter sets the value of the Description property for the object. The LDAP Display Name (ldapDisplayName) for this property is "description".

Type:String
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-Instance

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.

Type:ADReplicationSite
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-InterSiteTopologyGenerator

The server acting as the inter-site topology generator for this site.

Type:ADDirectoryServer
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-ManagedBy

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.

-ManagedBy ContosoAdmins

Type:ADPrincipal
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-OtherAttributes

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"}

Type:Hashtable
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-PassThru

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-ProtectedFromAccidentalDeletion

Specifies whether to prevent the object from being deleted. When this property is set to true, you cannot delete the corresponding object without changing the value of the property. Possible values for this parameter include:

$false or 0

$true or 1

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

-ProtectedFromAccidentalDeletion $true

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.

The following example shows how to specify a full qualified domain name as the parameter value.
