Thanks for that. 10 hours 24 minutes sounds about right so if I lower
the TTL it will refresh quicker. Why is it that when I reboot the server
my home computer can't use the same caching information as it did
before. Does it change or something. I'm using a ipcop box as my gateway
to the net at home i'm not sure what to do. The TTL thing only needs
updating when things change in the zone file right or wrong. People
always recomend that TTL so shall I lower the TTL time.
