I get the following error when backing up using NTBackup and similar when using SBS2003 backup.
"Backup Status
Operation: Backup
Active backup destination: File
Media name: "Backup.bkf created 3/07/2010 at 10:19 AM"
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."
Have SBS2003 SP2. Have tried clean boot, all suggested updates (None appeared to be required for SP2), and "re-registering related Dll files" to no effect. NTBackup works OK for non-administrative users where I assume volume shadow copy is not used. Both backup programs working perfectly until two weeks ago. Backups have been to additional drive in computer and/or to external USB drive.
