The "Network connection lost" message indicates that the network connection between the PCoIP Zero Client and PCoIP Remote Workstation Card, HP Anyware PCoIP Agent or VMware View virtual desktop host is down or disrupted.  This provides an indication to users that the information on their display may be stale.  There is a fast trigger for this message which is a requirement for real-time sensitive applications such as command and control and investment trader workstations.  

Note that as a result of the fast trigger, the "Network Connection Lost" message can be falsely triggered repeatedly by a virtual machine host that is busy due to process scheduling on the server.  As such, it is recommended that this message be disabled for connections to virtual desktop sessions. Newer Firmware disables this setting by default. It can be turned on through the AWI or using the PCoIP Management Console

Common steps for avoiding this message - make sure:

  • That the Ethernet cables are connected properly to the PCoIP Zero Client, PCoIP Remote Workstation Card, and network devices (e.g., switches).
  • That the network is not experiencing congestion due to capacity issues
  • That the ESXi server has enough processing power to service the VM's within best practices for VDI.
