We are seeing an issue with workstations not detecting a network
connection when they first boot up and consequently they enable
workstation only mode. If we press ESC to refresh the login window then a
net connection is detected and we can login fine.

We just noticed this issue today but we're not sure if it's a switch
config issue or e client setting in the image, which we updated recently.
We are using Client v4.91.3.20061109.

Any ideas would be greatly appreciated.
