Repairing Volume Shadow Copy Services

One of my coworkers at Adoni Networks ran into an issue tonight where backup software wouldn’t run.  The first software Acronis Trueimage kept crashing with the following error:

faulting application TrueImageService.exe  faulting module TrueImageService.exe fault address 0x00450f9c

After several attempts to correct the problem we switched to a backup software, DriveImage XML.  It failed backup while complaining that volume shadow services were not running however when he checked the services volume shadow copy showed running.

Checking the event logs revealed the following error:

Volume Shadow Copy Service initialization error: the control dispatcher cannot be started [0x80070427].

After some digging he found the folloiwng Microsoft Article: http://support.microsoft.com/kb/940032

The article details the following Steps to reregister Volume Shadow copy services:

1. Click Start, click Run, type cmd, and then click OK.
2. Type the following commands at a command prompt. Press ENTER after you type each command.

cd /d %windir%\system32
Net stop vss
Net stop swprv
regsvr32 ole32.dll
regsvr32 oleaut32.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

Note The last command may not run successfully.

3. Perform a backup operation to verify that the issue is resolved.
