Logon failure with Win32 Service using Domain Account

[firec++]

I am trying to install a local service under the context of a trusted domain account.

I installed the service correctly and it starts fine running under the LocalSystem context, however the service fails to start under the domain account because of a logon failure.

The domain account I am using meets all of the following requirements. Please tell me if I am missing anything:

1). Account is enabled/unlocked
2). Account password I am using is valid (logged into a few machines with it)
3). Account has local admin rights on the machine I am installing the service on

Attached is the CreateService() function I am using to install the service.

Thank you

     TCHAR szPath[MAX_PATH] = (L"\"C:\\Program Files\\Temp.exe\"");
     TCHAR szStartName[50] = (L"Domain\\User");
     TCHAR szStartNamePassword[50] = (L"**********");

      schService = CreateService( 
            schSCManager,
            SVCNAME,
            SVCNAME,
            SERVICE_ALL_ACCESS, 
            SERVICE_WIN32_OWN_PROCESS, 
            SERVICE_AUTO_START,
            SERVICE_ERROR_NORMAL,
            szPath,
            NULL,
            NULL,
            NULL,
            szStartName,
            szStartNamePassword);
