DNS_ERROR_SCOPE_LOCKED

DNS_ERROR_SCOPE_LOCKED means the policy scope cannot be changed because DNS is processing another configuration operation that holds a lock on it.

Avoid simultaneous policy and scope changes from different administration sessions or automation jobs.
Refresh the current configuration and wait for the previous operation to finish before retrying.
Check the DNS Server event log if the lock persists, because a failed configuration transaction may be the real issue.
