I've been getting this event as part of the problem with MS Software Shadow Copy Provider service. Symptoms: Component Service woudn't expand. MS Provider service woudn't start. Error error 0x8000ffff when trying to run regsvr32 /i swprv.dll or vssadmin list providers Here is how I fixed it. 1) Deleted registry entry for SwPrv. (In fact some application deleted the service before, but I've imported it from the other computer). This is to allow COM+ app import later. 2) Deleted com3 key and COM+ folders as per messages and links above. Rebooted. This is to re-install COM+ 3) Re-installed COM+ as per links above and MS recommendations. Now I was able to expand Component Services down to My Computer, but there was no MS Provider application there. 4) From the working computer with the same OS version I've exported MS Software Shadow Copy Provider application. To do so, Start Component Services, expand to "COM+ Applications", right-click on "MS ... Provider" name and choose "Export" from the menu. On the next screen choose "Export user identities with roles" It will ask you for file name and location and it will create MSI package. Copy the package to the troubled computer. 5) On the computer-in-need: - start component services - expand to "my computer" node - right-click on "COM+ Applications" and choose "new" --> "Application" - choose "Install pre-built application" button and navigate to the MSI package. Keep all defaults. After the process completes, there is proper COM+ application as well as the service installed. If there is any errors during the process, there is some left-over running and it is necessary to clean the registry and reboot then repeat COM+ install. At this point you should be able to start both Shadow Copy-ralated services. I had correct reply yto vssadmin list providers (it was error 0x8000ffff before) I was getting an error 0x8000ffff in reply to vssadmin list writers and Event ID 8193 was logged in the App log. Backup was working at this point but without Shadow Copy. Then I followed the steps from http://blogs.technet.com/sdoakes/archive/2.../03/418722.aspx which I copy for conveniece here with my comments. 1. 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 ------- I was able to register it, before Iwas getting error 0x8000ffff regsvr32 /i eventcls.dll regsvr32 es.dll regsvr32 stdprov.dll regsvr32 vssui.dll -------- I had XP, I guess this should work for 2003 only. regsvr32 msxml.dll -------- the last 3 depend on what XML versions you have installed. regsvr32 msxml3.dll -------- if you get error here, re-install corresponding XML version regsvr32 msxml4.dll 2. After completing the registration of the DLL’s open an command prompt and type: vssadmin list writers 3. You should see the writers listed. 4. Open Ntbackup and attempt to backup file or systemstate.
