We occasionally experiece an annoying situation where the contents on /etc/hosts is removed from the applaine - this I assume is a result from our locally configured hosts file been over-written with a default version.
The hosts file contains local Windows Domain Controller IP info, and when this event occurs, all NTLM authentication activities stop within a few minutes of incident.
Currently using version 7.3, but this event has occurred with previous versions in the past.
Typically not all appliances in our clusters are affected, but interestingly this time all our physical appliances were affected ( a majority of appliances are Virtual ).
Whereas the resolution is simple ( copy current hosts file to affected appliance ), I am wondering if any of my fellow WebGateway Admins have experienced the same problem.
