Hi. I have been backing up my windows 7 PC using WHS2011 dashboard successfully for 6 months, however a few days ago I initiated a manual backup and it failed with Incomplete status. Since then every backup I try to do takes hours and hours to even get to 2% and I end up cancelling the backup because I can't wait any longer. Looking in the win 7 event viewer I am seeing a VSS error 8194
Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied.
. This is often caused by incorrect security settings in either the writer or requestor process.
Operation:
Gathering Writer Data
Context:
Writer Class Id: {e8132975-6f93-4464-a53e-1050253ae220}
Writer Name: System Writer
Writer Instance ID: {7702bf03-b4b3-49c4-8d04-be3390fc1ae4}
I have run vssadmin and listed the states of all the writers and 2 appear to be stuck
Writer name: 'MSSearch Service Writer'

can anybody help me resolve this problem? My other xp PC and the WHS server backup work fine so it looks like a windows 7 PC problem.
