NtstatushACCESSDENIED

NtstatushACCESSDENIED is not an officially documented NTSTATUS code in Windows development resources. It appears to be a misspelling, a nonstandard label, or a misinterpretation found in some logs or codebases. The canonical NTSTATUS value associated with similar meaning is STATUS_ACCESS_DENIED.

STATUS_ACCESS_DENIED indicates that the caller does not have the necessary access rights to perform the requested operation on a securable object. It is used by the Windows kernel and various subsystems to signal insufficient permissions. The numeric NTSTATUS representation is 0xC0000022, and in many user-mode scenarios the condition can be translated to the Win32 error ERROR_ACCESS_DENIED.

In practice, this status can occur in a wide range of contexts, including attempting to open, read, write, or modify files; accessing registry keys; interacting with service or driver objects; or performing privileged operations without the required rights. It often arises from access control lists (ACLs) or security descriptors that deny the requesting token’s privileges, or from an impersonation scenario where the effective token lacks the needed rights.

Resolution typically involves verifying and adjusting permissions. Actions may include reviewing ACLs on the object, ensuring correct ownership, acquiring the appropriate user rights (such as SeBackupPrivilege or SeSecurityPrivilege where applicable), or running with elevated privileges. Tools such as security auditing, icacls, or process token inspection can aid in diagnosing the cause of the denial.
