I pushed software updates to a collection consisting of 116 computers. All of these machines are using the same agent policies, and are nearly identical in hardware and are all running Windows 7 Pro SP1 64-bit. The majority of machines returned success after
the users or the Agent executed the system restart. However, 16 machines returned error 0x87D00667, which I have discovered means:
"No current or future service window exists to install software updates"
I configured the deployment not to use a maintenance window, but to install immediately after the available time. I configured the available time to be about a week-long period of time.
The majority of machines behaved correctly and didn't wait for a maintenance window. However these 16 machines decided that the updates couldn't be installed outside of a maintenance window. Why would nearly identical machines with the same policies behave differently?
There was only one configured maintenance window for this collection, one that had already passed and was non-recurring. Can anybody shed some light on this?
