Hi Jac, 1. Please apply the hotfix mentioned in the following KB artilce A VSS hardware snapshot database keeps growing with duplicated snapshot information when it is updated for snapshot creation/deletion in Windows Server 2008 or in Windows Vista SP1 systems http://support.microsoft.com/kb/959476 2. Run the vssadmin utility and using the “vssadmin list writers” and "vssadmin list providers". 3. Register the dlls that are needed by the VSS service. From command prompt: Cd windows\system32 Net stop vss Net stop swprv regsvr32 ole32.dll regsvr32 vss_ps.dll Vssvc /Register regsvr32 /i swprv.dll regsvr32 /i eventcls.dll regsvr32 es.dll regsvr32 stdprov.dll regsvr32 vssui.dll regsvr32 msxml.dll regsvr32 msxml3.dll regsvr32 msxml4.dll 4.

Do you know if there is a hotfix for Server 2008 SBS x64? I have gone to the link you have provided but when I download it and try to install it, it gives me an error that this patch is the wrong version for my server.
