I also learned that you can at least partially protect against this type of hash being captured by checking out this article, which has you set the following setting in GPO:

  • Under Computer Configuration > Policies > Windows Settings > Security Settings > Local Policies > Security Options set Interactive logon: Number of previous logons to cache to 0. Be careful, as you will have login problems if a domain controller is not immediately accessible!
