- The calling program encountered the documented result: Only administrators have permission to add, remove, or configure server software during a Terminal services remote session. If you want to install or configure software on the server, contact your network administrator.
- A configuration, resource, or dependency used by the services and drivers operation did not meet its requirements
- A recent program, service, installer, or system change altered the context in which 0X80070668 occurs
Symptoms
- Confirm which operation returned 0x80070668
- Match 0x80070668 to events from the same timestamp
- Retest once and preserve any changed result
Prevention
- Preserve Application and System events that accompany 0X80070668
