Adding Server Core Roles in the Task Sequence
We are deploying Hyper-V Server to Dell M610 blades using Configuration Manager OSD. Deploying servers, as opposed to workstations, has some different challenges, though much is the same. In particular it’s critical to manage the drivers as tightly as you would with a workstation deployment. We’ve suffered a few BSOD’s from having out of date drivers…
When deploying the OS we want to add some roles for clustering, DotNet, Powershell, etc. It turns out that the MDT Add Roles task isn’t particularly aware of Server Core or Hyper-V Server, so the DotNet and PowerShell commands don’t work. This isn’t a big deal, as we can just use DISM commands. So,to install DotNet 2, we execute:
DISM /Online /Enable-Feature /FeatureName:NetFx2-ServerCore
NB This is case sensitive. It is also critical to disable 64-bit file system redirection, if you don’t, the 32-bit Configuration Manager agent will execute DISM from SYSWOW64 and you will receive an error in the Task Sequence status messages “The operating system reported error code 11: An attempt was made to load a program with an incorrect format”
