I have been using a Win 8 Hyper V VM with snapshots to test some applications I am writing in fresh environments (to ensure that it works in a non dev environment,etc)
The way I use it is that I create a snapshot after a fresh install, install my application, test and then revert to the snapshot I had created.
This works fine, except that after a few weeks, I get an error message related to "trust relationship between workstation and primary domain failed"
Is there a way to prevent this issue? (other than updating the clean snapshot every few days)?
