The DNS client does not utilize each of the DNS servers listed in TCP/IP configuration for each query. By default, on startup the DNS client will attempt to utilize the server in the Preferred DNS server entry. If this server fails to respond for any reason, the DNS client will switch to the server listed in the alternate DNS server entry. The DNS client will continue to use this alternate DNS server until:
(1) It fails to respond to a DNS query, or:
(2) The ServerPriorityTimeLimit value is reached (15 minutes by default). |
