You sent us the information:
First of all for your uefi policy you don’t have a value for dhcp option 66. Actually you can just remove that because it will pick the default values. Also your policies don’t look right you have values in the vendor column. Look through this article it tells you how to setup uefi policies: https://wiki.fogproject.org/wiki/index.php/BIOS_and_UEFI_Co-Existence#Using_Windows_Server_2012_.28R1_and_later.29_DHCP_Policy
You will want to create one policy for arch 007 and arch 009 for both types of UEFI.
Because Lenovo ThinkStation P340 Tiny not conected to Fog Server, but still not connecting to fog after setting the policy.
What else could we do?How could you help us?
Thank very much.
