Hi all, Very strange issue here, maybe somebody has seen that before?!
I'm currently building a new image with MDT 2013, patch the whole thing and later remove the reference to the MDT WSUS (I delete the HKLM\Software\Policies\Microsoft\Windows\WindowsUpdate key). Now I try to deploy it via ConfigMgr 2012 R2 CU4 and the client won't pick up any updates, every other distribution works, just not Software Updates. The key in the registry is empty. WUServer is missing. All the other ConfigMgr functionalities are working fine (Software Distribution, OSD, etc) Cheers David
