I'm trying to do a post to a local url in my network using this
code, but I'm getting 401 error (HTTP/1.1 401 Unauthorized), what can I do? or search for? (the machine where I running this is out the domain)

    TMemoryStream *aStream = new TMemoryStream();
    TStringStream *StrStream = new TStringStream(NULL);

    TStringList *a = new TStringList();
    TIdURI *uri = new TIdURI("");
    TIdMultiPartFormDataStream *Params = new   TIdMultiPartFormDataStream();

    Params->AddFormField("tarjeta", codta);
    Params->AddFormField("tipo", tipo);
    Params->AddFormField("monto", monto);
    Params->AddFormField("cargo", cargo);
    Params->AddFormField("idcajero", idcajero);
    Params->AddFormField("cajero", cajero);

    IdHTTP1->Request->Clear();
    IdHTTP1->Request->BasicAuthentication = true;
    IdHTTP1->Request->Username = txtUser->Text;
    IdHTTP1->Request->Password = txtPwd->Text;

    IdHTTP1->Post(txtUrl->Text, Params, aStream);

    aStream->Seek(0, soFromBeginning);
    aStream->SaveToStream(StrStream);
    StrStream->Seek(0, soFromBeginning);

    ShowMessage(StrStream->DataString);

    delete a;
    delete aStream;
    delete Params;
    delete uri;
    delete StrStream;
