Directory Services


The IADsGroup::Remove method removes the specified user object from this group. The operation does not remove the group object itself even when there is no member remaining in the group.

HRESULT Remove( 
  BSTR bstrItemToBeRemoved


[in] Contains a BSTR that specifies the ADsPath of the object to remove from the group. For more information about this parameter, see the Remarks section.

Return Values

The following are the most common return values. For more information about return values, see ADSI Error Codes.
Return Code/Value Description
The object was successfully removed.
The object specified by the bstrItemToBeRemoved parameter is not a member of the group.


If the LDAP provider is used to bind to the IADsGroup object, the same form of ADsPath must be specified in the bstrItemToBeRemoved parameter. For example, if the ADsPath used to bind to the IADsGroup object includes a server, the ADsPath in the bstrItemToBeRemoved parameter must contain the same server prefix. Likewise, if a serverless path is used to bind to the IADsGroup object, the bstrItemToBeRemoved parameter must also contain a serverless path. The exception is when adding or removing a member using a GUID or SID ADsPath. In this case, a serverless path should always be used in bstrItemToBeRemoved.

You can use a SID in the ADsPath to remove a security principal from the group through the WinNT provider. For example, suppose the SID of a user, "Fabrikam\jeffsmith", is S-1-5-21-35135249072896, the following statement:

Dim group As IADsGroup

is equivalent to

Dim group As IADsGroup

Removing a member using its SID through the WinNT provider is a new feature in Windows 2000 and the DSCLIENT package.

Example Code [Visual Basic]

The following code example removes a user account from a group.

Dim grp As IADsGroup
On Error GoTo Cleanup

Set grp = GetObject("WinNT://Fabrikam/Administrators")
grp.Remove ("WinNT://Fabrikam/jeffsmith")

	If (Err.Number<>0) Then
		MsgBox("An error has occurred. " & Err.Number)
	End If
	Set grp = Nothing

Example Code [C++]

The following code example removes a user from a group.

IADsGroup *pGroup = NULL;
LPWSTR usrPath = L"WinNT://Fabrikam/jeffsmith";
LPWSTR grpPath = L"WinNT://Fabrikam/Administrators";

hr = ADsGetObject(grpPath, IID_IADsGroup, (void**)&pGroup);
if(FAILED(hr)){goto Cleanup;}

hr = pGroup->Remove(CComBSTR(usrPath));
if(FAILED(hr)){goto Cleanup;}
