I am seeing some strange behaviour by my AMT clients (HP DC7700 and Intel DQ9656GF). This is the second time i am experiencing this behaviour in a few months and both times it happened just after sending my clients a power-off command using the AMT DTK's remote stack and then quering the power state.
What happens is that the clients do switch off, but they then become unavailable, exactly as one would expect them to behave if they had been provisioned with AMT available in the ON. The problem is that these clients have all been provisioned for AMT to always be on, i have verified this. When i manually switch the clients on again i can communicate with them as normal, but from that point onwards they are always unavailable when switched off. This problem happened yesterday, today the clients are acting normal again.
I am using the Intel SCS 3.0 to provision my clients and use the DTK's remote stack to communicate with my clients. I will be re-installing my server during the day and will be reprovisioning my clients. I will let you know if the problem happens again.
