I'm running WSUS 3.0 w/SP2 (3.2.7600.226) to patch dozens of domain controllers. Everything works well except some domain controllers that we patch (seems to happen randomly overseas in Europe, but not all the time). The updates install and when the server goes to reboot (around 3am) it just hangs, but, all that's involved in getting the server to continue its reboot is simply moving the mouse or pressing a key on the keyboard
(from the console of course). After that happens its as if the server wakes up and remembers what it has to do and does it. I don't understand this....we are able to patch many other DCs just fine. Servers reboot manually without a problem - this keyboard/mouse movement is only required with WSUS reboots.
I know this is an issue out there as I lifted the question from here:
I built all of these servers and they all run the same software/OS. The only pattern I can find is that the DCs that have issues are on Dell hardware (instead of normal IBM hardware elsewhere) with remote management, and they're overseas.
