Registry.RegistryConnect

I am trying to access a list of SID values on a remote server using TRegistry. This is the code:

Uses Registry;

procedure MyProc;
var
  MySList : TStringList;
  MyReg : TRegistry;
  i : Integer;
begin
  MyReg := TRegistry.Create;
  If MyReg.RegistryConnect('\\RemoteServer') then
  begin
    If MyReg.OpenKeyReadOnly('\HKEY_USERS') then
    begin
      MySlist := TStringList.Create;
      MyReg.GetKeyNames(MySList);
      {Do Something with the string list}
      MyReg.CloseKey;
      MySList.Free;
    end
    else
    ShowMessage('Cannot read HKEY_USERS on remote server');
  end;
  MyReg.Free;
end;

I receive the error that the key cannot be read. I can access these values using a component I downloaded. Unfortunately the component does not have the functionality to read key values- which I need later.
The 3rd party component allows a username and password to be provided for the remote server, I think this problem I am having could be a security one.
Could someone please inform me if this is the case or let me know if I am doing something else wrong. If this is a security problem then does anyone know how I can provide a username and password before connecting to the remote registry.

I have just realisted, with a bit of tinkering, that when I use registry connect my rootkey is as follows:

\\RemoteServer\HK_CURRENT_USER\{MYSID}

Does anyone know I can change the root key to
\\RemoteServer\HK_USERS

Using MyReg.Rootkey := HK_USERS would set it back to the local machine.

From Delphi help:

Note:     Before calling RegistryConnect, an application must set the RootKey property for its registry object to HKEY_USERS or HKEY_LOCAL_MACHINE.

//Otherwise it will revert back to the Local machine.

I've been looking at this problem all day and the answer has been staring my right in the face. In the examples I done earlier the first bit of code I wrote after creating the registry wrapper was to set the rootkey to HKey_Users. In my last example I forgot to do this.
Thanks fo your help, the program is working now.
