Hola yo uso este procedimiento

uses DB, ADODB, Variants, ActiveX, 
     ComObj, AdoInt, OleDB; 

procedure ListAvailableSQLServers(Names : TStrings);
var
  RSCon: ADORecordsetConstruction;
  Rowset: IRowset;
  SourcesRowset: ISourcesRowset;
  SourcesRecordset: _Recordset;
  SourcesName, SourcesType: TField;

    function PtCreateADOObject(const ClassID: TGUID): IUnknown;
    var
      Status: HResult;
      FPUControlWord: Word;
    begin
      asm
        FNSTCW FPUControlWord
      end;
      Status := CoCreateInstance(CLASS_Recordset,nil,CLSCTX_INPROC_SERVER or CLSCTX_LOCAL_SERVER,IUnknown,Result);
      asm
        FNCLEX
        FLDCW FPUControlWord
      end;
      OleCheck(Status);
    end;
begin
  SourcesRecordset :=PtCreateADOObject(CLASS_Recordset) as _Recordset;
  RSCon := SourcesRecordset as ADORecordsetConstruction;
  SourcesRowset := CreateComObject(ProgIDToClassID('SQLOLEDB Enumerator')) as ISourcesRowset;
  OleCheck(SourcesRowset.GetSourcesRowset(nil,IRowset, 0, nil,IUnknown(Rowset)));
  RSCon.Rowset := RowSet;
  with TADODataSet.Create(nil) do
  try
    Recordset := SourcesRecordset;
    SourcesName := FieldByName('SOURCES_NAME');
    SourcesType := FieldByName('SOURCES_TYPE');
    Names.BeginUpdate;
    try
      while not EOF do
      begin
        if (SourcesType.AsInteger = DBSOURCETYPE_DATASOURCE) and (SourcesName.AsString <> '') then
          Names.Add(SourcesName.AsString);
        Next;
      end;
    finally
      Names.EndUpdate;
    end;
  finally
    Free;
  end;
end;
