Description

The New-ADReplicationSite cmdlet is used to create 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

Example 1: Create a replication site

PS C:\> New-ADReplicationSite -Name "NorthAmerica"

This command creates a new site named NorthAmerica.

Example 2: Create a replication site and set a property for it

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

This command creates a new site named Europe, and sets the AutomaticInterSiteTopologyGenerationEnabled property on the new object.

Example 3: Create a replication site and set its replication schedule

PS C:\> $Schedule = New-Object -TypeName System.DirectoryServices.ActiveDirectory.ActiveDirectorySchedule
PS C:\> $Schedule.ResetSchedule()
PS C:\> $Schedule.SetDailySchedule("Twenty","Zero","TwentyTwo","Thirty");
PS C:\> New-ADReplicationSite -Name "Asia" -ReplicationSchedule $schedule

This example creates a new site named Asia, and sets the daily ReplicationSchedule from 20:00 to 22:30.

Parameters

-AuthType

Specifies the authentication method to use. The acceptable values for this parameter are:

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.

Type:	ADAuthType
Accepted values:	Negotiate, Basic
Position:	Named
Default value:	Microsoft.ActiveDirectory.Management.AuthType.Negotiate
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-AutomaticInterSiteTopologyGenerationEnabled

Indicates whether the cmdlet prevents the Knowledge Consistency Checker (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
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-AutomaticTopologyGenerationEnabled

Indicates whether to enable automatic topology generation. 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
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:	SwitchParameter
Aliases:	cf
Position:	Named
Default value:	False
Required:	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
Required:	False
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 Lightweight Directory Access Protocol (LDAP) display name (ldapDisplayName) for this property is description.

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
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.

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.

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.

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
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-InterSiteTopologyGenerator

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

Type:	ADDirectoryServer
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-ManagedBy

Specifies the user or group that manages the object by providing one of the following property values:

Distinguished name
GUID (objectGUID)
Security identifier (objectSid)
SAM account name (sAMAccountName)

Note: The identifier in parentheses is the LDAP display name for the property.

This parameter sets the Active Directory attribute with an LDAP display name of managedBy.

Type:	ADPrincipal
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-Name

Specifies a name for the replication site object.

Type:	String
Position:	0
Default value:	None
Required:	True
Accept pipeline input:	True
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 LDAP display name (ldapDisplayName) defined for it in the Active Directory schema.

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;...}

Type:	Hashtable
Position:	Named
Default value:	None

Default value:	None
Required:	False
Accept pipeline input:	True

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-TopologyCleanupEnabled

Indicates whether the cmdlet enables topology cleanup. When enabled, prevents the KCC from removing connection objects that it does not need. Disable this option if you want to take responsibility for removing old redundant connections. Alternatively, to control or augment the topology, you can use manual connections, which the KCC does not delete.

Type:	Boolean
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-TopologyDetectStaleEnabled

Indicates whether the cmdlet enables topology detect stale. Prevents the KCC from excluding servers that are unreachable from the topology; that is, the KCC does use an alternate server to reroute replication. Use this option only if network communication is very unstable and brief outages are expected.

Type:	Boolean
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-TopologyMinimumHopsEnabled

Type:	Boolean
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-UniversalGroupCachingEnabled

Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False
