Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

If this is the error you are getting "0xa00084ca - The data being read from the media is inconsistent." then unless you have OFO and the exchange option then this is normal behavior :(
