We have a closed LAN that has PCs, PNAs (N5242A), and a PXA (N9030A) on that network. We have noticed that occasionally the PNAs sometimes revert back to the Windows 7 default policy settings despite having group policy working just fine on the other networked devices. The PCs and the PXAs are normal. I have gone over the group policies for all of them and they are set to the proper DoD Win 7 specifications. I was wondering if anything else has come across this issue?
