So we're setting up a new WDS only server for a Windows 10 deployment. The WDS side of things is super basic. Server 2012 R2. Win10 1511 x64. Boot answer file and image answer file. It appears the PC is getting renamed while offline after joining the domain, thus breaking the trust relationship. I cannot find the cause. The initial name is WIN-%SOMEVARIABLE%, the final name, which has a broken trust relationship is DESKTOP-%SOMEVARIABLE%. NOWHERE in the answer files have we specified a computer name. I've also changed the default WDS naming policy to something else to see if it changes either of these names and it doesn't. I'm completely stumped.
