Error returned while creating the volume shadow copy:8004231f

Hello

I am currently having a problem with my NTbackup. When I run try to run a
backup I get the following error

Error returned while creating the volume shadow copy:8004231f

I am running windows 2003 SBS SP2

It looks like it has to do with the VSS writers. Here is my vssadmin list
