SYMPTOMS

Consider the following scenario:
  • You use the socket function to create an ICMPv6 raw socket in Windows Server 2003.
  • You build an ICMP header. Additionally, you set the value of icmp6_cksum to 0.
  • You use the API sendto function to send the created package.
In this scenario, the value of the icmp6_cksum field in the icmp6_hdr structure is still 0 in the transmitted packet. This behavior does not comply with the RFC 3542 requirements. This behavior causes the functions of some applications to fail if the following conditions are true:
  • The application uses the ICMPv6 protocol.
  • The application expects Windows Server 2003 to set the value of the icmp6_cksum field.

CAUSE

Windows Server 2003 does not comply with the RFC 3542 requirements to set the value of the icmp6_cksum field.
