Under certain circumstances in Microsoft Windows Server 2003, the heavy use of Winsock programs may exhaust the system's non-paged pool memory. This behavior is likely to occur if the Winsock program is dealing with both Out-of-Band (MSG_OOB) traffic and standard TCP traffic. In this situation, you may experience various error messages and poor performance. Additionally, the system may stop responding (hang).
If the Winsock program does not read the incoming data from Winsock, the AfdB pool tag may buffer more data than is optimal. This behavior may exhaust all available non-paged pool memory.
This update has been superseded by another update. For more information about the replacement fix, click the following article number to view the article in the Microsoft Knowledge Base:

Technical support for x64-based versions of Microsoft WindowsIf 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.
