SCCM This Computer is not Registered with the Microsoft Endpoint Configuration Manager Site

Hello,

I am trying to setup SCCM to install a Dell Inspiron 3190 with a Dell USB ethernet adapter.

I have entered the laptop into SCCM with the correct MAC address, updated membership. When I network boot it allows me to log into SCCM and immediately gives the error:

This Computer is not Registered with the Microsoft Endpoint Configuration Manager Site.

I am pretty new to SCCM so at a loss where to start looking for a solution, my googling was fruitless so I hope someone can give me some advice

Thanks

Although this is quite an old question, as I just had the same problem and did not find any real answer, I figured I would still answer here so that the next person looking for this might find help here.

The problem lies within the concept of the passthrough MAC address, that many laptops without LAN Port use. In theory a good idea, the device itself presents a MAC to the USB NIC so that the concept of MAC = unique to a device is not violated. Many systems rely on this (so does SCCM for the initial identification). Unfortunately it has to be supported by the driver.

So what seems to happen in this case is:

  • PXE supports the feature and finds the TS

  • WinPE does not support the feature, suddenly your MAC changes and it does not find the TS anymore.

Possible workarounds:

  • Disable the passthough feature in the BIOS and use the MAC of the USB adapter (potentially bad, e.g. if you use one adapter for OSD of many devices this will always lead to problems)

  • Add the correct driver for the USB Device to your boot image (also do not forget to install it to your real OS, otherwise this will not be a problem for the TS but possibly later for your DHCP). If you go for this remember that different devices have different drivers, in our case we had done it for the WD19 dock but not the small USB dongle, so only one worked.
