SYMPTOMS

Consider the following scenario:
  • You use the socket function to create an Internet Control Message Protocol for IPv6 (ICMPv6) raw socket on a computer that is running Windows Server 2003.
  • You build an ICMP header and set the value of icmp6_cksum field to 0.
  • You use the sendto API function to send the created package.
  • Security update 953230 that is documented in the security bulletin MS08-037 is installed on the computer.
In this scenario, the value of the icmp6_cksum field in the icmp6_hdr structure keeps the value of 0 in the transmitted packet. This behavior does not comply with the Request for Comment (RFC) 3542 requirements. Additionally, the functions of some applications fail if the following conditions are true:
  • The application uses the ICMPv6 protocol.
  • The application expects that Windows Server 2003 will set the value of the icmp6_cksum field.

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.
