Symptom Workaround
When you carry on some operations like rename on files or folders on a Cluster Shared Volume (“CSV”) it may fail. The error message in this case is STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5). The issue occurs when the process does not have administrator right. As a workaround follow either of the methods –

  • Carry out the operation from a process that has administrator right.
  • Carry out the operation from a node that doesn’t have CSV ownership.

Microsoft is trying to resolve this problem and will push a patch in an upcoming release.

After installing this cumulative update and rebooting with Hyper-V enabled you may automatically enter BitLocker recovery mode and receive error 0xC0210000. Kindly see KB4505821 for the solution.
