Authentication issues on ethernet port

[waqas]

Hi Wim,
Thanks for getting back, we've been trying the same web page but it has not helped.

There are basically 2 ways mentioned on the web page to enable MAC pass-through,

Opion 1)
GUI and registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\XXXX Both essentially do the same thing but this setting reverts to default every time a new Dock is plugged.

Remote script push is not an option here as the laptop will keep creating new Driver keys for new docks and script is only one off.

Option 2)
Manual update of Registry key or Supplied script HKEY_LOCAL_MACHINE\System\CurrentControlSet\servic es\dlcdcncm\Parameters\

This option does nothing, we've tried on two laptops with latest Displaylink 8.3 driver and latest USB host driver with several docking stations and it made no difference.
we also updated registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\servic es\dlcdcncm_x64\Parameters\ but it did not help.


There is no displaylink customer service so We're trying to engage docking station vendor to get some support but it has not helped so far, issue is still open.

Thanks for your assistance here.
