Microsoft Surface Book or Surface Pro dock PXE boot returns "unable to mount KBOX share" (4295461)

When trying to iPXE boot Microsoft UEFI Surface Book and/or Surface Pro (Windows 10) systems an error is returned, "Cannot mount KBOX share".  

Criteria where the problem has been experienced:

1. Microsoft's official "Surface Dock"  docking station or dongle is being used.
2. iPXE booting for other UEFI systems (e.g. Lenovo, Dell, HP) can successfully PXE boot. 
3. KSDA appliance is at version 4.0.695 or up.
4. Microsoft ADK 1511 or later is installed.
5. WinPE 10 is installed in the driver share. 

Workaround:

1. Verify that the KSDA appliance is at version 4.0.695 or up.
2. Confirm that Microsoft ADK 1511 or higher is installed and WinPE 10 driver package is installed in the driver share.  Troubleshoot and verify that no other drivers are installed that could be conflicting with the driver share.
3. Official Microsoft dongle or docking station is being used to connect a Surface Pro or Surface Book device.
4. PXE boot the device until the message, "cannot mount kbox share" appears.
5. Unplug the docking station/dongle, wait a few seconds (maybe up to 10 seconds), then plug it back into the network environment.
6. From the command prompt, type "startnet.cmd" (without the double quotes) then press enter.  Verify that the device can now connect to the KBE menu.  

This is not an issue with the KSDA (KACE System Deployment Appliance), but an issue with the Microsoft docking station/dongle device.
