Windows 7 users in my domain are unable to configure or change backup settings. Users are able to open Control Panel > Backup and Restore, but when they clickChange settings, they receive the error: Windows Backup - The backup application coud not start due to an internal error: You must be logged on as an administrator to perform this task. (0x8100000010).
The same error is received when executing sdclt.exe /configure at the command prompt, regardless of whether the command prompt is launched using "run as administrator".
I've done significant testing, and have been able to determine that the local administrator account is able to configure backups before the computer is joined to the domain. Once the computer is joined to the domain, the local administrator account and domain users who are in the local administrators group are no longer able to configure backup and restore. Domain administrators are able to configure backups.
This is a new issue, which began occuring sometime in the last 2 months. 3 months ago, users were able to configure backups without issue, and those computers with backups configured are still able to run their backups and do restores; however the settings can no longer be changed.
Clearly something in the domain is doing this, but Group Policy has not been altered, and I can find no setting that would be doing this in any case. Any help is appreciated.
