During configuration, an IP address is set in the Intel AMT device. This IP address is used by management consoles (and Intel SCS) to remotely connect to Intel AMT.
Solutions:
The first step is to check the IP address that is defined in the Intel AMT device. To do this, use the standalone Discovery Utility or the SystemDiscovery command. For more information, see Discovering Systems.
The value of the IP address is located in this tag/registry key:
Configurationinfo > AMTNetworkSettings > AMTWiredNetworkAdapter > IPv4IPSettings > IP.
To fix this problem, it is recommended to run this command on the Intel AMT system to immediately update the IP address: ipconfig /renew
After the IP address is correctly defined in the Intel AMT device, all remote connections should work without any problems.
