I have had problems with the WSUS updates failing for at least a year. I maintain 80 computer systems all offline. I download the updates on my fileserver then run them individually from the server. I cloned 24 new machines last November of those machines I can do updates on 21 of them now the other 3 stopped working. They use the same files. The other 50 + systems stopped working months ago. Because I am totally offline I have been going to Microsoft and getting the patches from them and loading individually.
Is there any suggestions on where to look to get it working again???
