Sorry I didn't reply sooner Javier, we just changed forums and I initially lost my e-mail updates that there were new posts.

It sounds like SCS wasn't able to fully provision the system, if "Delayed" is showing up in the status.  If SCS got the hello packet, but wasn't able to get back to the system to finish the configuration (if there were DHCP problems this could happen), it wouldn't be fully configured.  That would explain why the WebUI for the system isn't coming up, since until the AMT system hears back from SCS (or some other configuration server), it's not provisioned yet.  One option is that you clear the system out of SCS and reprovision.  You could either put Activator on the system to kick off hello packets again, or reset and reconfigure the AMT system.

The other possibility is that something isn't set right in the AMT system that is preventing SCS from connecting.  How did you initially setup the AMT system for provisioning?  Did you use a USB key, or did you manually enter data into the ME?  For either option, could you tell me what options you set when you were configuring the AMT system?
