Last month, I noticed that some 2008R2 servers weren't updating anymore from my 2012R2 WSUS server (it's using SSL, by the way), with error 80072EFE. On the WSUS Server, somewhere between october and november, was installed KB2992611.
I solved it by installing manually KB2992611 and KB3018238 and the non updating server.
Today I made a Win7 32 bit machine from scratch, using the official ISO from VLSC (with SP1) and the client was giving me error 80072EFE when trying to update from WSUS. Installing KB2992611 from Windows Update solved the problem and the machine started to get updates from my WSUS.
Is there something to do to avoid this problem at all? I'm joining a lot of already working clients from other domains to mine and I wouldn't have to check one by one if the need manual patching to work with my WSUS...
