| Event Id | 6527 |
| Source | DNS |
| Description | Zone <zone name> expired before it could obtain a successful zone transfer or update from a master server acting as its source for the zone. The zone has been shut down. |
| Event Information | CAUSE: This event ID might appear when the DNS server is configured to host a secondary copy of the zone from another DNS server acting as its source or master server. Verify that this server has network connectivity to its configured master server. If the problem continues, consider one or more of the following options: Delete the zone and recreate it, specifying either a different master server, or an updated and corrected IP address for the same master server. If zone expiration continues, consider adjusting the expire interval. |
