SBS Backup error

[ElAguila]

I have been trying to backup small businiess server 2003. It backed up fine last week. Now I am getting a couple of different errors. One says:

"Error returned while creating the volume shadow copy:0x80042319.

I can try the backup again and it will say:

"Unexpected error DeviceIoControl(\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy76".

I have looked it up on the internet and have followed these suggestions. I installed the KB891957-x86-ENU.exe and the KB940349-v3-x86-ENU.exe hotfixes. I also performed these commands from the prompt and it still fails after rebooting. Any other things I can try? I am trying to just backup 2 text files that I made to a test and it is a no go. I am running Small Business Server 2003 with Service Pack 2 using ntbackup gui.

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

regsvr32 msxml4.dll

I did some more searching and I have tried a couple of other things including clearing the shadow copies, creating a new shadow copy, and clearing the eventlogs. Still no luck. What I can't figure out is that the backups were working fine last week. No software has installed or removed and now all of a sudden this is happening.
