[<CommonParameters>] Description
The Get-ADReplicationConnection cmdlet returns a specific Active Directory replication connection or a set of AD 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 Knowledge Consistency Checker (KCC) reuses existing connections where it can, deletes unused connections, and creates new connections if none exist that meet the current need.

Parameters
-AuthType
Specifies the authentication method to use. Possible values for this parameter include:
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.
The following example shows how to set this parameter to Basic.
-AuthType Basic
| Type: | ADAuthType |
| Accepted values: | Negotiate, Basic |
| Position: | Named |
| Default value: | Microsoft.ActiveDirectory.Management.AuthType.Negotiate |
| Required: | False |
| 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 The following example shows how to create credentials.
$AdminCredentials = Get-Credential "Domain01\User01"
The following shows how to set the Credential parameter to these credentials.
-Credential $AdminCredentials
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 |
| Required: | False |
| 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, see 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.
Examples:
The following examples show how to use this syntax with Active Directory cmdlets.
To get all objects of the type specified by the cmdlet, use the asterisk wildcard:
All user objects:
Get-ADUser -Filter *
-or-
All computer objects:
Get-ADComputer -Filter *
To get all user objects that have an e-mail message attribute, use one of the following commands:
Get-ADUser -Filter "EmailAddress -like '*'"
Get-ADUser -Filter "mail -like '*'"
-or-
Get-ADObject -Filter "(mail -like '*') -and (ObjectClass -eq 'user')"
Note: PowerShell wildcards other than "*", such as "?" are not supported by the Filter syntax.
To get all users objects that have surname of Smith and that have an e-mail attribute, use one of the following commands:
Get-ADUser -Filter "(EmailAddress -like '*') -and (Surname -eq 'smith')"
-or-
Get-ADUser -Filter "(mail -eq '*') -and (sn -eq 'Smith')"
To get all user objects who have not logged on since January 1, 2007, use the following commands:
$logonDate = New-Object System.DateTime(2007, 1, 1)
Get-ADUser -Filter "lastLogon -le '$logonDate'"
To get all groups that have a group category of Security and a group scope of Global, use one of the following commands:
Get-ADGroup -Filter "GroupCategory -eq 'Security' -and GroupScope -eq 'Global'"
-or-
Get-ADGroup -Filter "GroupType -band 0x80000000"
Note: To query using LDAP query strings, use the LDAPFilter parameter.
| 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.
Distinguished Name
Example: CN=saradavis,OU=users,OU=asia,DC=corp,DC=contoso,DC=com
GUID (objectGUID)
Example: 599c3d2e-f72d-4d20-8a88-030d99495f20
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.
This example shows how to set this parameter to an ADObject object instance named "ADObjectInstance".
-Identity $ADObjectInstance
| Type: | ADReplicationConnection |
| Position: | 0 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| 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. The following examples show how to retrieve properties for a group where the Administrator's group is used as the sample group object.
Get-ADGroup -Identity Administrators | Get-Member
To retrieve and display the list of all the properties for an ADGroup object, use the following command:
Get-ADGroup -Identity Administrators -Properties *| Get-Member
The following examples show how to use the Properties parameter to retrieve individual properties as well as the default, extended or complete set of properties.
To retrieve the extended properties "OfficePhone" and "Organization" and the default properties of an ADUser object named "SaraDavis", use the following command:
GetADUser -Identity SaraDavis -Properties OfficePhone,Organization
To retrieve the properties with LDAP display names of "otherTelephone" and "otherMobile", in addition to the default properties for the same user, use the following command:
GetADUser -Identity SaraDavis -Properties otherTelephone, otherMobile |Get-Member
| Type: | String[] |
| Aliases: | Property |
| Position: | Named |
| Default value: | None |
| Required: | False |
| 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
Examples: corp.contoso.com
NetBIOS name
Example: CORP
Directory server values:
Fully qualified directory server name
Example: corp-DC12.corp.contoso.com
NetBIOS name
Example: corp-DC12
Fully qualified directory server name and port
Example: corp-DC12.corp.contoso.com:3268
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 Windows PowerShell.
The following example shows how to specify a full qualified domain name as the parameter value.
-Server "corp.contoso.com"
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
Inputs
None or Microsoft.ActiveDirectory.Management.ADReplicationConnection
A connection object is received by the Identity parameter.
