Server state backup

Hi everyone,

Hope all is well. Sorry have not been about lately but i have had a week of carnage with 2 festivals and some gigs. so its about time i bugged u with something.

Set up a backup system but the only thing that wont backup is the server state from windows backup. when i check the log file it gives me this message.

Backup Status
Operation: Backup
Active backup destination: File
Media name: "system state server.bkf created 31/08/2006 at 00:00"

Volume shadow copy creation: Attempt 1.
"Event Log Writer" has reported an error 0x800423f4. This is part of System State. The backup cannot continue.

Error returned while creating the volume shadow copy:800423f4
