Server Failed and Zone Expired Problems

When a secondary server cannot obtain updates from its master, it logs a master unreachable message. If the problem is not corrected, the secondary expires the zone and stops answering requests from clients. When that happens, users start seeing server failed messages.


Note that if the problem lies with a secondary server, some users could still be successfully obtaining DNS information from the master and thus operating without experiencing any difficulty.

Possible causes:

The two most likely causes for these problems are network failure and a wrong IP address for the master in the secondary's boot file.

Diagnosis and solution:

Make sure that the IP address of the master matches the master's actual IP address and the address for the master specified in the hosts file. If the IP address is wrong, correct it, and then reboot the secondary.
