Is above recovery for booting up in Safe Mode with Network connectivity BUT not joining domain?
Thing is our PCs have NAC (Network Access Control) such that we can't bring PCs from outside to connect up to our network. If so, while in "Safe Mode with Networkg", MS NAC may not work (though I've not tested it).
So how should we go about recovering an enabled local admin on Win 7 Enterprise?
It's to address audit requirement that we disable local administrator.
From above link, do we need only Win 7 DVD or do we need other DVDs as well?
