Question

我正在尝试通过C ++和ADO连接到同一域中不同计算机上的SQL Server 2008实例。我能够通过SQL Server Management Studio成功连接。但是通过传递相同的凭据，在我的C ++程序中，我收到错误：＆＃34;用户登录失败＆＃39; DOMAIN \ MyUserID＆＃39;。＆＃34;这是我尝试的代码：

HRESULT hr = -1;
CoInitialize(NULL);
try
{
    _ConnectionPtr pConn1("ADODB.Connection");
    _CommandPtr pCmd1("ADODB.Command");
    hr = pConn1.CreateInstance("ADODB.Connection");
    pConn1->Provider = "sqloledb";
    hr = pConn1->Open("Data Source='DATAXXX';Initial Catalog='DATA123';Integrated Security=SSPI", "XX", "xyz123", adConnectUnspecified);
    //hr value returned is : S_OK

}
catch (_com_error& ex)  //ex value is: DB_SEC_E_AUTH_FAILED Authentication failed
{
    CString err = ex.Description();
    AfxMessageBox(err); //err = Login failed for user 'DOMAIN\\MyUserID'
}

    if (hr != S_OK)
    {
        AfxMessageBox("ERROR: Opening Database connection");
        return;
    }
    pCmd1->ActiveConnection = pConn1;

请告诉我这里我做错了什么。我的操作系统是Windows 8，我使用的是VS2013
