Get-ADReplicationConnection

Returns a specific Active Directory replication connection or a set of AD replication connection objects based on a specified filter.

Description

The Get-ADReplicationConnection cmdlet returns a specific Active Directory replication connection or a set of Active Directory replication connection objects based on a specified filter. 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: Get all replication connections

PS C:\> Get-ADReplicationConnection -Filter *

This command gets all of the replication connections.

Example 2: Get all replication connections from a specified domain controller

PS C:\> Get-ADReplicationConnection -Filter {ReplicateFromDirectoryServer -eq "corp-DC01"}

This command gets all replication connections that replicate from corp-DC01.

Example 3: Get a specified replication connection

PS C:\> Get-ADReplicationConnection -Identity "5f98e288-19e0-47a0-9677-57f05ed54f6b"

This command gets the replication connection with the GUID 5f98e288-19e0-47a0-9677-57f05ed54f6b.

Example 4: Get the properties of a replication connection

PS C:\> Get-ADReplicationConnection -Identity "5f98e288-19e0-47a0-9677-57f05ed54f6b" -Properties *

This command gets all the properties of the replication connection with the GUID 5f98e288-19e0-47a0-9677-57f05ed54f6b.

Required Parameters

-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:ADReplicationConnection
Position:0
Default value:None
Accept pipeline input:True (ByValue)
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 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 PowerShell returns a terminating error.

Type:PSCredential
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-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>, see 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
-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

The default authentication method is Negotiate.

A Secure Sockets Layer (SSL) connection is required for the Basic authentication method.

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

Inputs

None or Microsoft.ActiveDirectory.Management.ADReplicationConnection

A connection object is received by the Identity parameter.

Outputs

Microsoft.ActiveDirectory.Management.ADReplicationConnection
