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.

-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.

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:
