DMP-8065 frequently losing connection to control computer, IPv6 causing NIC failure

Potential Symptoms

  • DMP-8065 frequently losing connection to control computer, IPv6 causing NIC failure.
  • DMP Event Viewer errors:
    • The ICS_IPV6 failed to configure IPv6 stack.
    • The UPnP Device Host service depends on the SSDP Discovery service which failed to start because of the following error: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.
    • The ICS_IPV6 was unable to allocate bytes of memory. This may indicate that the system is low on virtual memory, or that the memory manger has encountered an internal error.
  • Connection to the DMP via VNC, web configuration, or Venus 1500 will stop randomly and require a reset to resolve.
