On a Windows 2003 Server, I had the following problem. When looking at the properties of the disk and then the “Shadow Copies” tab, we received an error :

Error 0×8004230f:  the shadow copy provider had an unexpected error while trying to process the specified operation.

In the eventviewer I saw  the following error :

Event ID : 10005
Source : DCOM
DCOM got error “The service cannot be started, either because it is disabled or because it has no enabled devices associated with it. ” attempting to start the service swprv with arguments “” in order to run the server:
{65EE1DBA-8FF4-4A58-AC1C-3470EE2F376A}

Solution

I needed to register the swprv.dll again. Restart the VSS service and the problem was gone.

regsvr32 /i %windir%\system32\swprv.dll

Note: When migrating a machine using the VMWare Converter (from physical to virtual) I received the following error : FAILED: Unable to create a VSS snapshot of the source volume(s). Error code: 2147549183 (0×8000FFFF).
The solution above resulted in a clean migration process.
