I need a solution
This error points to a MS Technote ( http://support.microsoft.com/kb/980794 ) In it you are asked to create or edit a registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SystemWriter\ and then add the ExcludedBinaryPaths. My question is, does this mean to exclude all of the VSS systewm writers (ie.. from the command "vssadmin list writers" ) ?
