Windows instances timeout every 12 hours.

Solution In Progress - Updated -

Issue

  • Windows instances are losing network connectivity every 12 hours.
  • This is happening at the same time the DHCP lease is trying to renew.
  • In the event view DHCP client logs should show something like this message
The IP address lease XXXXXX for the Network Card with network address XXXXX has been denied by the DHCP server XXXXX (The DHCP Server sent a DHCPNACK message).
