SBS not backing up at all.  "Error returned while creating the volume shadow copy:0xffffffff."

My Exchange server isn't backing up at all.  I have 2 full backups set up to run nightly to 2 different external drives (at different times), both are giving this error in the backup logs:

"Backup Status
Operation: Backup
Active backup destination: File
Media name: "Small Business Server Backup (01).bkf created 10/30/2008 at 9:03 PM"

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.

----------------------

The operation did not successfully complete."

Server is Windows Server 2003 for Small Business Server, SP2.  I'm also getting this in my nightly report:

"VssAdmin: Unable to create a shadow copy: Another shadow copy creation is already in progress. Please wait a few moments and try again. Command-line: 'C:\WINDOWS\system32\vssadmin.exe Create Shadow /AutoRetry=5 /For=\\?\Volume{6e520954-201e-11dc-bf55-505054503030}\'. "

The attempted backup files themselves are always 2KB.  One of the backups is configured through NT Backup, and the other is configured through Active Directory (although I believe the one through AD still uses NT Backup).

The external drives that the file is backed up to are both highly fragmented (96% on one), which may be a factor.  However, I haven't had any luck defraggin them.

Any help would be greatly appreciated.

Thanks.

are you running mcaffee antivirus?  It can cause this problem.

try re-registering the following dlls by running the following commands:

net stop vss
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 apologize - I should have mentioned that, yes, I found that series of commands online, and I ran them, with no change.  And no, no McAffee - Symantec End Point Protection.  But the problem pre-dates installing the newest version of Symantec.  I had Symantec AntiVirus before, and it ran for months with no problems with my backup.

Thanks for the suggestion, tomcahill.
