 [-Instance <ADReplicationSiteLink>] [-PassThru] [-Server <String>] [<CommonParameters>]

DESCRIPTION

The Set-ADReplicationSiteLink cmdlet sets properties on an Active Directory site link. A site link connects two or more sites. Replication site links reflect the administrative policy for how sites interconnect and the methods used to transfer replication traffic. You must connect sites with site links so that domain controllers at each site can replicate Active Directory changes.

EXAMPLES

PS C:\> Set-ADReplicationSiteLink -Identity "Europe-Asia" -SitesIncluded @{Add="Asia2";Remove="Asia"}

This command adds the site Asia2 to the replication site link Europe-Asia, and removes the site Asia.

Example 2: Set a property on filtered sites

PS C:\> Get-ADReplicationSiteLink -Filter {ReplicationFrequencyInMinutes -ge 60} -Properties Cost | % {Set-ADReplicationSiteLink $_ -Cost 200}

This command gets all the site links in the directory with replication frequency greater than or equal to 60 minutes, and then sets the Cost property on these site link objects to 200.

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-ADReplicationSiteLink -Identity "NorthAmerica-SouthAmerica" -ReplicationSchedule $Schedule

This command sets the daily replication schedule of the site link with name NorthAmerica-SouthAmerica.

PS C:\> Set-ADReplicationSiteLink -Identity "Europe-Asia" -Replace @{'options'=1}

This command enables change notification on the site link with the name Europe-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 Lightweight Directory Access Protocol (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 will be performed in the following order:

  • Remove
  • Add
  • Replace
  • Clear
Type: Hashtable
Parameter Sets: Identity
Aliases: 

Required: False
Position: Named
Default value: None
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
Parameter Sets: (All)
Aliases: 
Accepted values: Negotiate, Basic

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

-Clear

Specifies an array of object properties that will be 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 will be performed in the following order:

  • Remove
  • Add
  • Replace
  • Clear
Type: String[]
Parameter Sets: Identity
Aliases: 

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

-Confirm

Prompts you for confirmation before running the cmdlet.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: cf

Required: False
Position: Named
Default value: False
Accept pipeline input: False
Accept wildcard characters: False

-Cost

Specifies the cost to be placed on the site link. For more information on determining the cost, see Determining the Cost in the TechNet Library: http://go.microsoft.com/fwlink/?LinkId=221871.

Type: Int32
Parameter Sets: Identity
Aliases: 

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

-Credential

Specifies the user account credentials to use to perform this task. The default credentials are the credentials of the currently logged on user unless the cmdlet is run from an Active Directory module for Windows PowerShell provider drive. If the cmdlet is run from such a provider drive, the account associated with the drive is the default.

To specify this parameter, you can type a user name, such as User1 or Domain01\User01 or you can specify a PSCredential object. If you specify a user name for this parameter, the cmdlet prompts for a password.

You can also create a PSCredential object by using a script or by using the Get-Credential cmdlet. You can then set the Credential parameter to the PSCredential object.

If the acting credentials do not have directory-level permission to perform the task, Active Directory module for Windows PowerShell returns a terminating error.

Type: PSCredential
Parameter Sets: (All)
Aliases: 

Required: False
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
Parameter Sets: Identity
Aliases: 

Required: False
Position: Named
Default value: None
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 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: ADReplicationSiteLink
Parameter Sets: Identity
Aliases: 

Required: True
Position: 0
Default value: None
Accept pipeline input: True (ByValue)
Accept wildcard characters: False

-Instance

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

You can use an instance of an existing site link object as a template or you can construct a new site link object by using the Windows PowerShell command line or by using a script.

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

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

Type: ADReplicationSiteLink
Parameter Sets: Instance
Aliases: 

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

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

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

-Remove

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

-Remove @{Attribute1LDAPDisplayName=value[]; Attribute2LDAPDisplayName=value[]}

When you use the Add, Remove, Replace, and Clear parameters together, the parameters will be applied in the following sequence:

  • Remove
  • Add
  • Replace
  • Clear
Type: Hashtable
Parameter Sets: Identity
Aliases: 

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

-Replace

Specifies values for an object property that will replace the current values. Use this parameter to replace 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:

-Replace @{Attribute1LDAPDisplayName=value[], Attribute2LDAPDisplayName=value[]}

When you use the Add, Remove, Replace, and Clear parameters together, the parameters will be applied in the following sequence:

  • Remove
  • Add
  • Replace
  • Clear
Type: Hashtable
Parameter Sets: Identity
Aliases: 

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

-ReplicationFrequencyInMinutes

Species the frequency, in minutes, for which replication will occur where this site link is in use between sites. Active Directory preserves bandwidth between sites by minimizing the frequency of replication and by allowing you to schedule the availability of site links for replication. By default, intersite replication across each site link occurs every 180 minutes (3 hours). You can adjust this frequency to match your specific needs. Be aware that increasing this frequency increases the amount of bandwidth used by replication.

Type: Int32
Parameter Sets: Identity
Aliases: 

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

-ReplicationSchedule

Specifies the default replication schedule for any connections within this site link (intra-site replication). This allows you to schedule the availability of site links for use by replication. By default, a site link is available to carry replication traffic 24 hours a day, 7 days a week. You can limit this schedule to specific days of the week and times of day. You can, for example, schedule intersite replication so that it only occurs after normal business hours.

Type: ActiveDirectorySchedule
Parameter Sets: Identity
Aliases: 

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

-Server

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 (FQDN)
  • NetBIOS name

Directory server values:

  • Fully qualified directory server name
  • NetBIOS name
  • 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.
Type: String
Parameter Sets: (All)
Aliases: 

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

-SitesIncluded

Specifies the list of sites included in the site link. For Set-ADReplicationSiteLink operations, you can add or include new sites within an existing site link by specifying them using this parameter. You do not have to specify all previously listed sites already within this link.

Type: Hashtable
Parameter Sets: Identity
Aliases: 

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