Some windows 8.1 domain machines fail to run or enforce a domain policy. The policies have been pushed and are visible in the workstations policy editor or RSOP.MSC however they intermittently fail to be enforced. Some example are. Workstation locking after 15 minutes of inactivity, Executable to be run for collecting asset inventory. Event logging and Scripts in general. We took 2 windows 8.1 laptop and two Windows 7 laptops and placed them in the same policy group. Screen saver was the most common visible failure. Both windows 7 machine consistently locked while the 8.1 machines failed about half the time. each machine sitting about 8 inches apart on the same table. At first we dismissed it as the machine sensitive may have been triggered. But not the case when an Inventory script failed to run part of the time on the windows 8.1 machines.
I can't find any known issues on the MSKB that describe this issue.
