Volume Shadow Servic e

Walt

The Volume Shadow Copy Service will not start, and generates errors in the
Event Log. Sample errors as follows:

Event ID 8193 Source VSS
Volume Shadow Copy Service error: Unexpected error calling
IEventSystem::Store.

Event ID 1000 Source Application Error
Faulty application vssvc.exe, version 6.0.6000.16386, time stamp 0x4549b1da,
faulting module ntdll.dll, etc.

MS Shadow Copy Provider service is set to manual, and can be started. RPC
is set to auto, and is started. VSC is set to manual, and cannot be
started. I have reregistered ole32.dll, vss.ps.dll, swprv.dll, stdprov.dll,
msxml3.dll and msxml4.dll.

I replaced vsvcc.exe with a known good copy, but it failed to reregister, as
did es.dll, and eventcls.dll.

I haven't tried replacing ntdll.dll with a known good yet.

Any ideas?

Thanks
Walt

Hi Walt--

Unfortunately for a number of reasons, there are some .dlls like those
components that just might not reregister because it's not simply a matter
of trying to replace them and reregistering them as you can in some
situations. If no joy from this list of error messages then here's what I'd
do:

http://blogs.technet.com/filecab/pa...-restore-and-complete-pc-backup-problems.aspx

Also take a look at Bert Kinney's resources here:

Missing Restore Points/Shadow Copies in Windows Vista:
http://bertk.mvps.org/html/missingrpv.html

http://bertk.mvps.org

If no joy from those links, here's how I'd fix it:

***SFC as a Remedy***:

SFC or System File Checker is a bit like the spare tire in your car or a
backup battery I suppose. In Vista of course, they have changed it somewhat
and come up with a new name--Redmond stands for name it something different
twice a year and now it's part of WRP or Windows Resource Protection. It
scans protected resources including thousands of files, libraries, critical
folders, and essential registry keys, and it replaces those that are
corrupted with intact ones. It fixes a lot of problems in Windows XP, OE,
Windows Vista, Win Mail, IE6, and on Vista or if it is installed on XP, IE7.
It protects these things from changes by any source including
administrators, by keeping a spare of most of them.


How to Run SFC:

Type "cmd" into the Search box above the Start Button>and when cmd comes up
at the top of the Start menu>right click cmd and click "run as Admin" and
when the cmd prompt comes up at the cmd prompt type "sfc /scannow" no quotes
and let it run. This may fix things quite a bit. It replaces corrupt files
with intact ones, if you're not familiar with it.


If you have a Vista DVD, you can try Startup Repair or a repair install.


***Startup Repair from the Vista DVD***

How to Use The Vista DVD to Repair Vista (Startup Repair is misnamed by the
Win RE team and it can be used to fix many Vista components even when you
can boot to Vista):

http://www.windowsvista.windowsreinstall.com/vistaultimate/repairstartup/index.htm

If you elect to run Startup repair from the Vista DVD (it can fix major
components in Vista--I've verified this many many times; it's good for more
than startup problems, and the Win RE team simply was wrong when they named
it, not understanding its full functionality):

Startup Repair will look like this when you put in the Vista DVD:

You run the startup repair tool this way (and system restore from here is
also sometimes effective but I understand you don't have system restore
working right now):

How To Run Startup Repair In Vista Ultimate (Multiple Screenshots)
http://www.windowsvista.windowsreinstall.com/vistaultimate/repairstartup/index.htm

It will automatically take you to this on your screen:

http://www.vistaclues.com/wp-content/uploads/2006/12/click-repair-your-computer.png

That will allow you to go to the Vista setup that has a Repair link on
thelower left corner>click it and then you'll see a gray backgrounded list
and I want you to click Startup Repair from it and follow the directions.

The gray screen after you click the first link in the above pic will look
like this:

http://www.windowsreinstall.com/winvista/images/repair/staruprepair/Image17.gif

Click Startup Repair, the link at the top and after it scans>click OK and
let it try to repair Vista. It will tell you if it does, and if it
doesn't, try System Restore from the Recovery Link on the DVD. If these
don't work booting into Safe Mode by tapping the F8 key and using System
Restore from one of the safe modes besides VGA may work. That means you
have the option to try 4 different safe modes to get to system restore, (one
from the Recovery link on the DVD) and sometimes one will work when the
others won't.

You could also try a Repair Install with Vista which is done exactly the
same way as in XP:
