    Hi Rodelio

    I'm Project Manager who implemented this NAC solution. I also open case to Microsoft Business support. There're no progress but this issue has more impact on users and business operation.

    So I just need to find someone hit with the same experience on me and do anyone resolve this?

    Thanks
