I was able to install the driver after I extracted the contents of the Dell EXE using 7-Zip.  You obviously shouldn't have to do that, but it works.
I tried installing the Server 2016 chipset driver on my R720XD but was met with the following error message: ''Update is terminated, as the lockdown mode is enabled. Disable the lockdown mode and try the update again" [IMAGE] The OS is the RTM version of Server 2016. Nothing else is installed, apart from Dell OMSA 8.4. The Hyper-V role is enabled with no VMs running. This is the driver I was trying to install: [URL] I was able to work-around the problem by extracting the installer with 7-zip and then running the Intel chipset installer directly. What is lockdown mode and how do I turn it off? Or is this a driver installer error?
