I mentioned some of the problems in my previous post. But these are
questions I have been looking for an answer for a while.

To change dns easier, I modify dns file directly. But after I do it, the
change can not updated to secondary DNS. Strange thing is when I modify the
domain on DNS (not the file), and change something, the change can tranfer
to my secondary server. But the change I did by modifying the dns file still
not transfer. How come it works that way? Any idea?

When you make a change by using the file, you need to increment the zone
serial before the secondary will request a zone transfer.
It is up to the secondary to request a zone transfer, if not using DNS
notify the secondary uses the refresh value to check for an updated zone.
All zone transfer are initiated by the secondary.

When using the console to make changes, the serial is automatically
incremented.

Do you increment or otherwise update the SERIAL number
so that it will be GREATER than the secondaries?

When you modify the file directly you are responsible for
getting EVERYTHING correct -- other than that, yes, you
can update the file although you may have to get the Primary
to reload the file afterwards.

(Above). In what way is modifying the file "easier"?
(I have done this when needing to make similar changes
to dozens of zones, but in general a simple change is
easier in the MMC.
