Your device may encounter an error “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. It occurs when you make an attempt to perform certain tasks (for example – renaming) on files or folders that are on a Cluster Shared Volume (CSV). This also happens to appear when you execute the operation on a CSV owner node from a process that doesn’t hold admin authorities.
As a temporary solution, you can try out any one of the following –
