Have you purchased NAC license ?
See Chetan Articles
Host Integrity, Peer-to-peer enforcement, and Quarantine policies, formerly part of Symantec Network Access Control, are now available for all users, regardless of whether or not they had purchased a SNAC license. This change does not grant users access to the NAC portion of the product, which still requires a Network Enforcer and a SNAC license that has been purchased separately. It should also be noted that this change does not apply to the Small Business Edition version of the SEP product. There is no actual change in Host Integrity or SNAC functionality related to this enhancement
