KB4512474 Known Issues

Issue #1: Performing certain operations like renaming of files or folders may result in an error message. The error message reads – “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. Only those files which are on cluster shared volume get affected due to this bug. 

Sol– The above trouble arises only if you perform the above operations on a CSV owner node using a Non-admin account. To solve this problem, you should follow either of these two options-
