Basically, you create an Authentication Policy Silo container and assign the desired user accounts and computers to that silo.

To prevent users accounts from bypassing silo restrictions by authenticating via NTLM, silo’d accounts must also be members of the new Protected Users group. Membership in Protected Users triggers a number of different controls designed to prevent pass-the-hash and related credential attacks – including disabling NTLM for member accounts.
