Configuring the Local Manageability Service

The Local Manageability Service (LMS) periodically requests the NAC posture from the Intel AMT device and saves it in the registry.

note-icon Note:

Beginning in Intel AMT Release 9.0 NAC is no longer supported in the FW but it is still supported in the SW.  Intel AMT 8.x Releases are able to run 9.0 SW.  Therefore, NAC would still be suppported on 9.0 SW running on 8.x FW.

Prior to Intel AMT Release 9.0, this functionality was done by the User Notification Service (UNS).  Below is a table summarizing when reporting will be done by UNS and when by LMS.

The posture plug-in is decoupled from the LMS and just reads the last posture value stored by the LMS without referring to when the posture was stored. The timing between the request to read and the actual storage time can be a critical parameter and depends on the settings of both the CTA and the LMS. The LMS requests a new posture every five minutes by default. IT administration can change this interval by adding a registry key (See below for the approach used starting with Release 4.0 through Release 8.1).

The key should be stored at: HKEY_LOCAL_MACHINE\SOFTWARE\Intel\IntelAMTUNS.

The key is a double word quantity: GetPostureInterval. The units are milliseconds. If the key exists and its value is less than 1000 milliseconds, the UNS request interval will default to one second.

For example, to set the interval to ten minutes, set GetPostureInterval to 600000.

The Intel AMT Release 4.0 UNS configuration file, IntelAMTUNS.conf contains the parameter GetPostureInterval. Enable and set the parameter there. The file is located at <root>:\Documents and Settings\All Users\Application Data in Windows XP installations, and at <root>:\ProgramData in Vista installations.
