I have a domain controller with over 50 PCs with limited internet access to these PCs. I managed to download packages for Windows 7, 8 and 8.1 for these clients and Server 2008 R2, 2012 R2 for servers.
The automatic patching of each client will be really painful for each machine. What I'm trying to do is to find a way to automate patching all machines over the network. Would you provide me with best practice to do this while I'm thinking of WSUS Server but I don't have to redownload all packages from Microsoft servers to patch domain machines. Is it possible to integrate offline WSUS offline packages into WSUS Server?
