Add me as another user seeing the same behavior - my linked-clone master image has IPV6 disabled, but linked clones deployed from that image (either through new pool creation or a recompose operation) are coming up with IPV6 enabled. I'm using Quickprep, and like the original poster we've been running this same config for over two years and not seen this behavior. This is with View 6.0.1 and VMtools 9.4.10 build-2068191.
Looks like a new network adapter is being created during VM spinup which would explain what's going on. Here are my network devices from my master image:
And here's a deployed linked clone:
So I guess something changed in VMtools, the View 6 Agent, or Composer that's causing this to happen?
