Cross posting from Windows 8 forum

Upgraded Windows 7 Pro to Windows 8 Pro.   Windows Home Server 2011 connector was installed and working prior to upgrade.  Backups complete without an error indication but attempting to restore files using the Windows Home Server 2011 Dashboard results in following messages displayed after choosing a backup to restore from (dies when the opening the volume operation gets to 4%):

The restore process did not succeed

This driver has been blocked from loading

I can successfully open the Windows 8's backup volume on a different Windows 7 machine from the Windows Home Server 2011 Dashboard.

I found a thread (http://social.microsoft.com/Forums/is/whs2011/thread/1271f38b-3831-4e42-a376-85bd975ca8e0) talking about a driver filter altitude conflict between the windows home server restore driver and Rapport but I don't have Rapport installed and did not find duplicates from fltmc:

C:\WINDOWS\system32>fltmc

Filter Name                     Num Instances    Altitude    Frame
------------------------------  -------------  ------------  -----
SiFilter                                        429998.99   <Legacy>
WdFilter                                7       328010         0
luafv                                   1       135000         0
npsvctrig                               1        46000         0
FileInfo                                7        45000         0

I have not uninstalled/re-installed the Windows Home Server 2011 connector software yet because I have not found out whether that will cause loss of my previous backups (including Windows 7) that I do not want to lose at this point.

TIA for any help resolving this,
