но единственная защита это Protected users (если нет проблем отключение ntlm)
Accounts that are members of the Protected Users group that authenticate to a Windows Server 2012 R2 domain are unable to:
- Authenticate with NTLM authentication.
- Use DES or RC4 encryption types in Kerberos pre-authentication.
- Be delegated with unconstrained or constrained delegation.
- Renew the Kerberos TGTs beyond the initial four-hour lifetime.
