DNS Troubles

[Callan, Chris]

Ok, I am running into some disturbing things. I have had DNS Entries
populate my main DNS server, that I have not entered.  I see them, and then
once I start looking around and refresh my zone.  The address is gone.  How
can I figure out how this is taking place.  I have never seen anything like
this and could really use some help.  I am running NT 4.0 SP 6a.
