NT Backup not running

Posted on 2008-10-20
Last Modified: 2011-12-01
We have a HP ML350 G4P server running SBS 2003 SP2.

Lately the backups have been failing. On checking the logs we have been getting the following errors:

1) Error: C: is not a valid drive, or you do not have access.
    Error: An inconsistency was encountered in the requested backup file.
    Error: D: is not a valid drive, or you do not have access.
    Error: An inconsistency was encountered in the requested backup file.
    Error: SLRESERVERQT\Microsoft Information Store\First Storage Group is not a valid drive, or you do not have access

2) Volume shadow copy creation: Attempt 1.
    Timeout before function completed
    Error returned while creating the volume shadow copy:0xffffffff.
    Error returned while creating the volume shadow copy:ffffffff
    Aborting Backup.

On checking the event logs i have noticed event ID 8193 - Volume Shadow Copy Service error: Unexpected error calling routine CoCreateInstance.  hr = 0x80040154
and event ID 20 - Volume Shadow Copy Service error: A critical component required by the Volume Shadow Copy service is not registered.  This might happened if an error occurred during Windows setup or during installation of a Shadow Copy provider.  The error returned from CoCreateInstance on class with CLSID {faf53cc4-bd73-4e36-83f1-2b23f46e513e} and Name VSSEvent is [0x80040154].

I have been doing heaps of research and have run numerous fixes including:

1) Re-registering the following .dll's:
> regsvr32 /s ole32.dll
> regsvr32 /s vss_ps.dll
> Vssvc /Register
> regsvr32 /s /i swprv.dll
> regsvr32 /s /i eventcls.dll
> regsvr32 /s es.dll
> regsvr32 /s stdprov.dll
> regsvr32 /s vssui.dll
> regsvr32 /s msxml.dll
> regsvr32 /s msxml3.dll
> regsvr32 /s msxml4.dll
I restarted the server and tried a backup but it failed with the same error (See error 2 at the top of this document).

I also tried to run the hotfix from KB article Number(s): 833167 which i believe was a VSS update but i was given an error saying that as i had SP2 installed there was no need to install this fix.

I have exhausted all the avenues i can think of and would appreciate any assistance in this case.

Many thanks

Have you reinstalled COM+ yet?
Seems like this worked for a few people I found on google.

A. To reinstall COM+, follow these steps:
1. Backup and then delete HKLM\Software\Microsoft\COM3
2. Boot to Recovery console and rename clbcatq.dll to ~clbcatq.dll. Be sure
to use the tilde.
3. Boot to normal mode and in Control Panel, open the Add or Remove
Programs tool, and then open the Add/Remove Windows Components tool. Do not
make any changes, just click "Next". This reinstalls COM+.

NOTE: You must have your Windows Server 2003 SP1 files available during
this step.

B. To register the services and binaries:
1. Stop the Volume Shadow Copy service: Open a command prompt and change
directories to \WINDOWS\system32 (this is important when you begin
registering the DLLs):

net stop vss

2. Then register the following DLLs and services (be sure you're still in
the WINDOWS\system32 directory at your command prompt):

regsvr32 ole32.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
regsvr32 msxml4.dll

Start the Volume Shadow Copy service by running "net start vss", do a test
backup and see how it goes.

Additionally, do i have to do the file renaming from the recovery console or can i do it in Windows?

I don't think it will let you do it from inside windows.

Hi, just got back from the site. I followed the procedures you detailed but alas it didn't work. Same error.
   Please note that while i was reinstalling COM+ in Add/Remove programs the following error was encountered:

Sub-component COM+ raised an exception while processing the OC_ABOUT_TO_COMMIT_QUEUE setup message. d:\nt\com\complus\src\complussetup\comsetup\csetuputil.cpp (line 3570) Error Code = 0x8007041b A stop control has been sent to a service that other running services are dependent on.The service control manager was unable to stop the 'EventSystem' service.
   Once i clicked OK to this message the installation seemed to complete without additional error. I was not prompted to insert any Windows CD's. I also checked the registry and the COM3 folder that i backed up and removed was back.

Any other suggestions would be greatly appreciated

I've been looking around and I can't think of anything else.  Perhaps its time to give Microsoft the 200 bucks and call =/
