Hyper-V VM cannot authenticate after applying snapshot or attaching VHD

If you encounter the following and tried dropping the machine from the domain and joining it back, do the following:

1.) First uninstall hidden adapters it will show as Local Area Connection #n. To do that follow the following in this site:

**it seems hyper-v adds 1 or 2 hidden network adapters.
2.) Removed the machine to the domain and add it to a work group
3.) Restart the machine
4.) Join the machine back to the domain

If all else fails create a new VM using a copy of the VHD you’re using. Do steps 1-4.
