   [[-Identity] <ADReplicationSite>]
   [-Properties <String[]>]
   [-Server <String>]

Description

The Get-ADReplicationSite cmdlet returns a specific Active Directory replication site or a set of replication site objects based on a specified filter. 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: Get all replication sites 

PS C:\> Get-ADReplicationSite -Filter *

This command gets all Active Directory Replication sites.

Example 2: Get replication sites by flag 

PS C:\> Get-ADReplicationSite -Properties * -Filter {WindowsServer2003KCCSiteLinkBridgingEnabled -eq $TRUE}

This command gets all sites that have the WindowsServer2003KCCBehaviorEnabled flag turned on. The Properties parameter must be set because the WindowsServer2003KCCSiteLinkBridgingEnabled property is not retrieved by default.

Example 3: Get replication sites by name 

PS C:\> Get-ADReplicationSite -Identity NorthAmerica

This command gets the site with name NorthAmerica.

Example 4: Get replication sites by name and property 

PS C:\> Get-ADReplicationSite -Identity NorthAmerica -Properties AutomaticInterSiteTopologyGenerationEnabled

This command gets the AutomaticInterSiteTopologyGenerationEnabled property of the site with name NorthAmerica.

Required Parameters

-Filter

Specifies a query string that retrieves Active Directory objects. This string uses the PowerShell Expression Language syntax. The PowerShell Expression Language syntax provides rich type-conversion support for value types received by the Filter parameter. The syntax uses an in-order representation, which means that the operator is placed between the operand and the value. For more information about the Filter parameter, type Get-Help about_ActiveDirectory_Filter .

Syntax:

The following syntax uses Backus-Naur form to show how to use the PowerShell Expression Language for this parameter.

<filter> ::= "{" <FilterComponentList> "}"

<FilterComponentList> ::= <FilterComponent> | <FilterComponent> <JoinOperator> <FilterComponent> | <NotOperator> <FilterComponent>

<FilterComponent> ::= <attr> <FilterOperator> <value> | "(" <FilterComponent> ")"

<FilterOperator> ::= "-eq" | "-le" | "-ge" | "-ne" | "-lt" | "-gt"| "-approx" | "-bor" | "-band" | "-recursivematch" | "-like" | "-notlike"

<JoinOperator> ::= "-and" | "-or"

<NotOperator> ::= "-not"

<attr> ::= <PropertyName> | <LDAPDisplayName of the attribute>

<value>::= <compare this value with an <attr> by using the specified <FilterOperator>>

For a list of supported types for <value>, type Get-Help about_ActiveDirectory_ObjectModel .

Note: PowerShell wildcards other than , such as ?, are not supported by the *Filter syntax.

Note: To query using LDAP query strings, use the LDAPFilter parameter.

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

Optional 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
Parameter Sets: Negotiate, Basic
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
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: ADReplicationSite
Position: 0
Default value: None
Accept pipeline input: True (ByValue)
Accept wildcard characters: False
-Properties

Specifies the properties of the output object to retrieve from the server. Use this parameter to retrieve properties that are not included in the default set.

Specify properties for this parameter as a comma-separated list of names. To display all of the attributes that are set on the object, specify * (asterisk).

To specify an individual extended property, use the name of the property. For properties that are not default or extended properties, you must specify the LDAP display name of the attribute.

To retrieve properties and display them for an object, you can use the Get-* cmdlet associated with the object and pass the output to the Get-Member cmdlet.

Type: String[]
Aliases: Property
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
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

Inputs

None or Microsoft.ActiveDirectory.Management.ADReplicationSite

A site object is received by the Identity parameter.

Outputs

Microsoft.ActiveDirectory.Management.ADReplicationSite
