Today I wanted to share a small tip if you got some problems with your Windows Server 2019 OEM Activation if you have OEM media.
I used the latest Dell OEM installation media in my case. When the virtual machine booted I used to get an activation error even if my key was valid.
Running a slmgr /ato returned me that error;
Error: 0x8007041D on a computer running Microsoft windows non-core edition, run ‘slui.exe 0x2a 0x8007041D ‘ to display the error text
At that point, even if I used my OEM media, I think it’s possibly a manufacturer problem with the media kit as in each of my cases I used to had a pre-installed version of ESX, and I selected to had the OEM OS.
To pass the activation the tip I got was simple, to use these customs settings inside the VM .vmx or parameters;
smbios.addHostVendor = TRUE
SMBIOS.reflectHost = TRUE
SMBIOS.noOEMStrings = TRUE
With those setting my virtual machine activated correctly 🙂
