MORE INFORMATION

A typical scenario for this problem occurs when you use Microsoft Dynamics AX. If a user's account belongs to 16 groups, the user cannot remotely access the Dynamics AX server. Specifically, the RpcGetAuthorizationContextForClient function fails, and then error code 0x18 is returned. This problem does not occur if the user belongs to any other number of groups.

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 must have 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 Windows Server 2003 x64 edition separately, contact Microsoft for technical support.
