Windows Server 2012 R2 has a check box called Protect Container From
Accidental Deletion for all OUs. If this check box is checked, to delete or

Resetting an Existing Computer Account
Every computer on the domain establishes a discrete channel of communication with the
domain controller at logon time. The domain controller stores a randomly selected pass-
word (different from the user password) for authentication across the channel. The pass-
word is updated every 30 days.

shown previously using an MMC snap-in. Well, this is going to be no different.
This example shows you how to reset the secure connection between the local computer
and the domain to which it is joined using a PowerShell command. In this example, the
