  • (Fix) Fixed an issue where Intel AMT returned inconsistent NAP posture hash results over SOAP/WS-MAN.
  • (Fix) Fixed an issue where Intel AMT might not acquire an IP address in DHCP active mode wWhen using DHCP Relay Agent software configured with "seconds-since-boot threshold" > 0.
  • (Fix) Fixed an issue where Intel AMT would accept DHCP ACK after DHCP transaction was complete.

  • (New) Added CyberTrust Root Certificate hashes (GTE CyberTrust Global Root, Baltimore CyberTrust Root and Cybertrust Global Root) into AMT 2.6.
  • (Fix) Changed the MEInfo error message to alert users of insufficient administrative rights when executing tool with non-administrative privileges on Windows 7.
  • (Fix) Fixed an issue where Wireless Intel AMT might fail to reconnect to the 802.11n Access Point with RSN-TLS profile in Hx after any link down/ link up cycle (SOL/IDER started/stopped in H0, wireless driver was disabled/enabled, Wireless Manageability disabled/enabled).
  • (Fix) Fixed an issue where it did not accept nor reject the connection, jamming LME's listening socket when HECI driver was disconnected and LME was requested to handle new connection (e.g., UNS event).
  • (Fix) Fixed an issue where AMT crashed when processing a malicious Kerberos token.
  • (Fix) Fixed an issue where SOL/IDER session might fail to open with 802.1x profile on some Access Points. Timeout was over before association process was completed.
