regsvr32 /i swprv.dll

regsvr32 /i eventcls.dll

regsvr32 vssui.dll

Vssvc /Register

regsvr32 ole32.dll

regsvr32 vss_ps.dll

regsvr32 es.dll

regsvr32 stdprov.dll

regsvr32 msxml3.dll

For Windows Server 2008 64bit

I get the same errors as "Excalibur". I continued on with the modifications but the VSS error still comes back.

How is this related to System Center Data Protection Manager? I am not running any System Center Products in my environment.

Please help!
Thanks!

5. Backup and delete the key.
Performed it.

6. Added the DWORD key MinDiffAreaFileSize with 3000 (as decimal, not hex)

7. Starting the services in the prescribed order;

No Events indicating a problem before restart.

8. Rebooting.

After reboot there's a new writer problem, new ID; instead of "SPSearch VSS Writer" it's "OSearch VSS Writer".

Additional info, the reg keys in the event have the following content;

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\Diag\WMI Writer]

As for HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\VssAccessControl
lists the expected service accounts.

However "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\Diag" does not contain the specific service accounts - nor the WSS local groups (WSS_ADMIN_WPG) in the permissions.
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\Diag" contains the WSS group (WSS_ADMIN_WPG) in permissions.

Hm, do we have a permission inheritance problem here?
I'll do a couple of tests.

EDIT; Adding the WSS_ADMIN_WPG with full control and inheritance for the sbubkeys did not help.

Hello I got excactly the same problem, except that i don't have a Data Protection Manager in my environment.

It seems that every hour, exactly at 27 Minutes (06:27, 07:27, 08:27) the server wants to do a VSS Backup (no idea why he does that and where this has been configured).

The MOSS 2007 Server is running on Windows Server 2008 x64.

Every hour he wants to do that VSS backup, the following error message appears:

Volume Shadow Copy Service error: Unexpected error RegOpenKeyExW(-2147483646,SYSTEM\CurrentControlSet\Services\VSS\Diag,...). hr = 0x80070005. Operation:

Hi,

For the case with volume shadow copy (VSS) and DPM, I resolved it by uninstalling the agent, disabled the firewall, and then reinstalled DPM agent.
I've left the FW off. Now the VSS error messageses are gone.

The installtion of the DPM agent doesn't do the job correct I assume...

I had the same problem, after deinstalling and reinstalling MOSS 2007.

It is obviously an access problem, with the two SharePoint service accounts (SPSearch and OSearch) not being able to access a key below ...\VSS\Diag as the error message states.

I right-clicked the Diag folder in the registry and brought up the Permissions dialog and allowed the two respective service accounts to have access. After that I haven't had any such error messages anymore.
