When I first provisioned a laptop all of the functionality in the OOB Console worked fine. A couple of days later the Serial over lan connection has stopped working.
In the OOBConsole.log I get the following
GETAMTPowerState fail with result:0x80070576
:IMR_SOLOpenTCPSession2 with user = domain\administrator fail with result: 0x19, description:Authentication failed
:IMR_SOLOpenTCPSession fail with result : 0x00000019.
I'm not sure what has changed to cause this
I'm running Windows 2003 SP2 R2 Ent Server, SCCM 2007 SP2 R2
Are you seeing this error if you try other AMT features, such as power control or IDE Redirection, or just when you launch a SOL session?
