विवरण
Query refused. The name server refuses to perform the requested operation for policy reasons.
जब आप इसे देखें
The server rejected your query due to access control — for example, a recursive resolver that only serves its own network, or a zone transfer blocked by ACL.
कैसे ठीक करें
Check the server's allow-query, allow-recursion, or allow-transfer ACLs. If you are not authorized to use this resolver, switch to a public DNS service.
विवरण
RR Set Exists when it should not. A resource record set exists that the update prerequisite says should not.
जब आप इसे देखें
A DNS UPDATE failed because a specific RRset (e.g., an A record) already exists when the prerequisite required it to be absent.
कैसे ठीक करें
Delete the conflicting RRset before retrying the update, or adjust your prerequisite conditions to match the actual zone state.
