Detailed Description
The Remove-ADGroupMember cmdlet removes one or more users, groups, service accounts, or computers from an Active Directory group.
The Identity parameter specifies the Active Directory group that contains the members to remove. You can identify a group by its distinguished name (DN), GUID, security identifier (SID), or Security Accounts Manager (SAM) account name. You can also specify a group object variable, such as $<localGroupObject>, or pass a group object through the pipeline to the Identity parameter. For example, you can use the Get-ADGroup cmdlet to retrieve a group object and then pass the object through the pipeline to the Remove-ADGroupMember cmdlet.
The Members parameter specifies the users, computers and groups to remove from the group specified by the Identity parameter. You can identify a user, computer or group by its distinguished name (DN), GUID, security identifier (SID), or Security Accounts Manager (SAM) account name. You can also specify user, computer, and group object variables, such as $<localUserObject>. If you are specifying more than one new member, use a comma-separated list. You cannot pass user, computer, or group objects through the pipeline to this cmdlet. To remove user, computer, or group objects from a group by using the pipeline, use the Remove-ADPrincipalGroupMembership cmdlet.
For AD LDS environments, the Partition parameter must be specified except in the following two conditions:
-The cmdlet is run from an Active Directory provider drive.
-A default naming context or partition is defined for the AD LDS environment. To specify a default naming context for an AD LDS environment, set the msDS-defaultNamingContext property of the Active Directory directory service agent (DSA) object (nTDSDSA) for the AD LDS instance.

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.
Default Value: **

Identity
Specifies an Active Directory group object by providing one of the following values. The identifier in parentheses is the LDAP display name for the attribute.
Distinguished Name
Example: CN=saradavisreports,OU=europe,CN=users,DC=corp,DC=contoso,DC=com
GUID (objectGUID)
Example: 599c3d2e-f72d-4d20-8a88-030d99495f20
Security Identifier (objectSid)
Example: S-1-5-21-3165297888-301567370-576410423-1103
Security Accounts Manager (SAM) Account Name (sAMAccountName)
Example: saradavisreports
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 the parameter to a distinguished name.
-Identity "CN=saradavisreports,OU=europe,CN=users,DC=corp,DC=contoso,DC=com"
This example shows how to set this parameter to a group object instance named "ADGroupInstance".
-Identity $ADGroupInstance

Members
Specifies a set of users, groups, and computers to remove from a group. You can identify users, groups, and computers by specifying one of the following values. Note: The identifier in parentheses is the LDAP display name.
Distinguished Name
Example: CN=SaraDavis,CN=Europe,CN=Users,DC=corp,DC=contoso,DC=com
GUID (objectGUID)
Example: 599c3d2e-f72d-4d20-8a88-030d99495f20
Security Identifier (objectSid)
Example: S-1-5-21-3165297888-301567370-576410423-1103
SAM Account Name (sAMAccountName)
Example: saradavis
You can also provide objects to this parameter directly.
The following examples show how to specify this parameter.
This example specifies a user and group to remove by specifying the distinguished name and the SAM Account Name property values.
-Members "CN=SaraDavis,CN=employees,CN=Users,DC=contoso,DC=com", "saradavisreports"
This example specifies a user and a group object that are defined in the current Windows PowerShell session as input for the parameter.
-Members $userObject, $groupObject
The objects specified for this parameter are processed as Microsoft.ActiveDirectory.Management.ADPrincipal objects. Derived types, such as the following are also received by this parameter.
Microsoft.ActiveDirectory.Management.ADUser
Microsoft.ActiveDirectory.Management.ADComputer
Microsoft.ActiveDirectory.Management.ADServiceAccount
Microsoft.ActiveDirectory.Management.ADGroup
You cannot pass objects through the pipeline to this parameter.

Partition
Specifies the distinguished name of an Active Directory partition. The distinguished name must be one of the naming contexts on the current directory server. The cmdlet searches this partition to find the object defined by the Identity parameter.
The following two examples show how to specify a value for this parameter.
-Partition "CN=Configuration,DC=EUROPE,DC=TEST,DC=CONTOSO,DC=COM"
-Partition "CN=Schema,CN=Configuration,DC=EUROPE,DC=TEST,DC=CONTOSO,DC=COM"
In many cases, a default value will be used for the Partition parameter if no value is specified. The rules for determining the default value are given below. Note that rules listed first are evaluated first and once a default value can be determined, no further rules will be evaluated.
In AD DS environments, a default value for Partition will be set in the following cases: - If the Identity parameter is set to a distinguished name, the default value of Partition is automatically generated from this distinguished name.
- If running cmdlets from an Active Directory provider drive, the default value of Partition is automatically generated from the current path in the drive.
- If none of the previous cases apply, the default value of Partition will be set to the default partition or naming context of the target domain.
In AD LDS environments, a default value for Partition will be set in the following cases:
- If the Identity parameter is set to a distinguished name, the default value of Partition is automatically generated from this distinguished name.
- If running cmdlets from an Active Directory provider drive, the default value of Partition is automatically generated from the current path in the drive.
- If the target AD LDS instance has a default naming context, the default value of Partition will be set to the default naming context. To specify a default naming context for an AD LDS environment, set the msDS-defaultNamingContext property of the Active Directory directory service agent (DSA) object (nTDSDSA) for the AD LDS instance.
- If none of the previous cases apply, the Partition parameter will not take any default value.

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:
