I have got Windows Storage Server 2008 running on a WD Sentinel DX4000. Recently my company bought a couple of new Dell laptops all running windows 8.1 64bit OS. Only three older laptops were left. Now for the fun part...I installed the connectors pointing to the Sentinel on the laptops, and as expected the pc's show on the dashboard of the Storage Server, but all of the backups fail on the newer laptops. I installed the connectors on the older laptops as well and they go through no problem
The only difference between the older laptops and the new ones are the GPT partition drives and laptops running on UEFI, the older laptops, although running the same OS, do not have GPT and UEFI. I looked at the Event Viewer and found three errors to do with the backup: Event 514 pointing to a ClientVSSProblem, Event 8194 pointing to Volume Shadow Copy Service error: Unexpected error querrying for the VSSWriterCallback interface, hr=0x80070005,Access Denied and the last one is Event 513 CAPI2, Cryptographic Service failed while processing onIdentity() call in the System Writerobject Details: AddLegacyDriverFiles: Unable to back up image of binary Microsoft Link-Layer Discovery Protocol. I did as most articles suggested but with no change. From changing registries to taking ownership of the %windir% and adding the NT AUTHORITY, the NT Service and BUILTIN\Users. No change.
Help is much appreciated before i make a boat anchor out of the WD Sentinel.
