Description

The Set-ADReplicationSite cmdlet is used to set the properties for an Active Directory site that is being used for 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: Set the replication site to prevent connections

PS C:\> Set-ADReplicationSite -Identity NorthAmerica -InterSiteTopologyGenerator corp-DC02 -AutomaticInterSiteTopologyGenerationEnabled $False

The command sets the properties of the site with name NorthAmerica to prevent its intersite topology generator (ISTG) at corp-DC02 from generating connections for intersite replication.

Example 2: Set replication start times for a filtered list of sites

PS C:\> Get-ADReplicationSite -Filter * | % {Set-ADReplicationSite $_ -ScheduleHashingEnabled $True}

This command returns all the sites in the directory and sets the ScheduleHashingEnabled property to spread replication start times randomly across the entire schedule interval rather than just the first quarter of the interval.

Example 3: Set the replication schedule for a site

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

This example sets the daily replication schedule of the site with name Asia.

Parameters

-Add

Specifies values to add to an object property. Use this parameter to add one or more values to a property that cannot be modified using a cmdlet parameter. To modify an object property, you must use the LDAP display name. You can specify multiple values to a property by specifying a comma-separated list of values and more than one property by separating them using a semicolon. The format for this parameter is:

-Add @{Attribute1LDAPDisplayName=value1, value2, ...; Attribute2LDAPDisplayName=value1, value2, ...; AttributeNLDAPDisplayName=value1, value2, ...}

When you use the Add, Remove, Replace, and Clear parameters together, the operations are performed in the following order:

Remove
Add
Replace
Clear

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

-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:	None
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:	False
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:	False
Accept wildcard characters:	False

-Clear

Specifies an array of object properties that are cleared in the directory. Use this parameter to clear one or more values of a property that cannot be modified using a cmdlet parameter. To modify an object property, you must use the LDAP display name. You can modify more than one property by specifying a comma-separated list. The format for this parameter is:

-Clear Attribute1LDAPDisplayName, Attribute2LDAPDisplayName

When you use the Add, Remove, Replace, and Clear parameters together, the operations are performed in the following order:

Remove
Add
Replace
Clear

Type:	String[]
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
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 LDAP Display Name (ldapDisplayName) for this property is description.

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

-Identity

Specifies an Active Directory object by providing one of the following property values. The identifier in parentheses is the LDAP display name for the attribute. The acceptable values for this parameter are:

A connection name
A distinguished name
A GUID (objectGUID)

The cmdlet searches the default naming context or partition to find the object. If two or more objects are found, the cmdlet returns a non-terminating error.

This parameter can also get this object through the pipeline or you can set this parameter to an object instance.

Type:	ADReplicationSite
Position:	0
Default value:	None
Required:	True
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 a cmdlet such as Get-ADReplicationSite. Then provide this 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 Active Directory object.

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

Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False

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

-WindowsServer2003KCCBehaviorEnabled

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

-WindowsServer2003KCCIgnoreScheduleEnabled

Indicates whether to ignore schedules. When the forest functional level Windows Server 2003 or Windows Server 2003 interim is in effect, provides KCC control of the ability to ignore schedules (replication occurs at the designated intervals and is always available).

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

-WindowsServer2003KCCSiteLinkBridgingEnabled
