Re: Strange DNS Behaviour



thanks kevin. yeah, I do read in another forum that AD will mess up the host
records at times.
but shouldnt there be a way where I can fix a primary IP since I have two?

it seems that Name Server->FQDN is supposed to serve the purpose, allowing
you to put multiple IP addresses in sequence, yet it is not obeying it. as
if it has a mind of its own, it will jumble up the IP sequence from time to
time.

my users have been using http://server1 to access the primary site since the
days of NT4, thus I am trying to resolve this at DNS level instead of using
host headers for the sake of users familiarization.
