A custom program that uses the RegConnectRegistry function can no longer access the registry of a remote computer in Windows Server 2003 with Service Pack 1 or in an x64-based version of Windows Server 2003

After you apply Microsoft Windows Server 2003 Service Pack 1 (SP1) or install an x64-based version of Windows Server 2003, a custom program that uses the RegConnectRegistry function can no longer access the registry of a remote computer.

This problem may affect computers that are running Microsoft Systems Management Server (SMS) 2003. For example, a Windows Server 2003-based server that is running SMS 2003 may be unable to access the registry on a remote server. Additionally, the SMS 2003 server log file may contain an entry that is similar to the following: Note This problem only occurs when SMS 2003 is running in advanced security mode.

This problem occurs because the RegConnectRegistry function incorrectly uses the security context of the anonymous logon account to connect to the remote computer. The RegConnectRegistry function does not use the account that the function used before you installed Windows Server 2003 SP1.

Technical support for x64-based versions of Microsoft Windows

Your hardware manufacturer provides technical support and assistance for x64-based versions of Windows. Your hardware manufacturer provides support because an x64-based version of Windows was included with your hardware. Your hardware manufacturer might have customized the installation of Windows with 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 your x64-based version of Windows. 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.
