SYMPTOMS
Consider the following scenario. You use a program that uses the IADsOpenDSObject::OpenDSObject method to specify a user principal name (UPN) for the user ID during logon. This user ID is specified during logon to a Microsoft Windows Server 2003 domain. However, if a user types the wrong password in this scenario, the number of unsuccessful logon attempts is not incremented by the authenticating domain controller, as indicated by the badPwdCount value.



WORKAROUND
To work around this problem, do not use the UPN for the user ID. Instead, use \  for the user ID.

Technical support for x64-based versions of Microsoft Windows
If your hardware came with a Microsoft Windows x64 edition already installed, your hardware manufacturer provides technical support and assistance for the Windows x64 edition. In this case, your hardware manufacturer provides support because a Windows x64 edition was included with your hardware. Your hardware manufacturer might have customized the Windows x64 edition installation by using unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with a Windows x64 edition. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware. If you purchased a Windows x64 edition such as a Microsoft Windows Server 2003 x64 edition separately, contact Microsoft for technical support.
