We are going to need a few more details before we can root cause this issue. please tell me the make and model of the platform your using, the BIOS version, the ME FW version - this comes up as two pieces when you boot. At the top of the screen is the ME BIOS extension and as it initializes you will see a FW version string, (i.e. 22.214.171.1244). It also appears that you are using Microsoft SCCM console so I need to know if you are using Cerberus encryption on the network, or 802.1x authentication. lastly can you just open a web browser and enter the ip address + :1699x (x=2 un secure HTTP or 3=secure HTTPS), if you can get a login in screen please capture it.
