Description

The Set-ADReplicationConnection cmdlet sets properties on Active Directory replication connections. Connections are used to enable domain controllers to replicate with each other. A connection defines a one-way, inbound route from one domain controller, the source, to another domain controller, the destination. The Kerberos consistency checker (KCC) reuses existing connections where it can, deletes unused connections, and creates new connections if none exist that meet the current need.

Examples

Example 1: Set a replication connection to a specified domain controller

PS C:\> Set-ADReplicationConnection -Identity "5f98e288-19e0-47a0-9677-57f05ed54f6b" -ReplicateFromDirectoryServer corp-DC01

This command sets the replication connection with GUID 5f98e288-19e0-47a0-9677-57f05ed54f6b to replicate from corp-DC01.

Example 2: Set a daily 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:\> Get-ADReplicationConnection -Filter "ReplicateFromDirectoryServer -eq 'corp-DC01'" -Properties ReplicationSchedule | % {Set-ADReplicationConnection $_ - ReplicationSchedule $Schedule}

This command gets all of the replication connections in the directory that replicates from corp-DC01, and then sets the daily replication schedule on these connection objects.

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

Accepted values:	Negotiate, Basic
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 are 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

-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.

Derived types, such as the following are also accepted:

• Microsoft.ActiveDirectory.Management.ADGroup
• Microsoft.ActiveDirectory.Management.ADUser
• Microsoft.ActiveDirectory.Management.ADComputer
• Microsoft.ActiveDirectory.Management.ADServiceAccount
• Microsoft.ActiveDirectory.Management.ADFineGrainedPasswordPolicy
• Microsoft.ActiveDirectory.Management.ADDomain

Type:	ADReplicationConnection
Position:	0
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-Instance

Specifies an instance of an Active Directory object to use as a template for a new Active Directory object.

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

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

Method 2: Create a new ADObject and set the property values by using the Windows PowerShell command line interface. Then pass this object to the Instance parameter of the New-ADObject 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:	ADReplicationConnection
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
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
Position:	Named
Default value:	None
Required:	False
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 are applied in the following sequence:

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 operations are performed in the following order:

• Remove
• Add
• Replace
• Clear

Type:	Hashtable
Position:	Named
Default value:	None
Required:	False

-ReplicateFromDirectoryServer

Specifies the domain controller to use as a source for this replication connection.

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

-ReplicationSchedule

Specifies the schedule on which the source server is available for replication.

Replication occurs at intervals that administrators can schedule so that use of expensive WAN links is managed. Use this parameter to specify the replication intervals. For more information on how replication topology works, see How Active Directory Replication Topology Works on TechNet.

To specify the replication schedule:

1. Create a new Active Directory schedule object. For example:

   $Schedule = New-Object -TypeName System.DirectoryServices.ActiveDirectory.ActiveDirectorySchedule;

2. Edit the schedule on the Active Directory schedule object. For example:

   $Schedule.ResetSchedule();

   $Schedule.SetDailySchedule("Twenty","Zero","TwentyTwo","Thirty");

3. Using the Active Directory schedule object, set the replication schedule of the connection.

   Set-ADReplicationConnection "5f98e288-19e0-47a0-9677-57f05ed54f6b" -ReplicationSchedule $Schedule.

For more information on the ActiveDirectorySchedule class, see ActiveDirectorySchedule Class on the Microsoft Developer Network.

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

-Server

Specifies the Active Directory Domain Services (AD DS) 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 Directory Services (AD LDS), AD DS, or Active Directory snapshot instance.

Specify the AD DS instance in one of the following ways:

Domain name values:

• Fully qualified domain name
• NetBIOS name

Directory server values:

• Fully qualified directory server name
• NetBIOS name
• Fully qualified directory server name and port

The default value for this parameter is determined by one of the following methods in the order that they are listed:

• By using the Server value from objects passed through the pipeline
• By using the server information associated with the AD DS Windows PowerShell provider drive, when the cmdlet runs in that drive
• By using the domain of the computer running Windows PowerShell

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