How to set up this?

When set up "Primary DNS suffix of this computer', there
is this 'Change primary DNS suffix when domain membership
changes' check box, the default is checked.

What does this box do? When should I just leave it as is
and when should I uncheck it? Any reference?

Thanks in advance!
 
I don't have references handy, so let me just do a brain-dump here.
A suffix is like a lastname/surname. It tells your client (computer) that
"when I ask for Deji, ALWAYS assume that I am asking for Deji AKOMOLAFE". In
computer world, let's say your DomainName is "DomainName.com", the suffix
tells the computer "if I say I am looking for Computer1, always assume that
I am looking for Computer1.DomainName.com"

The "change Primary DNS suffix when domain Membership changes" part is a
convenience for when you move a computer out of a doamin and join it to
another domain and forget to manually change the suffix. This check box
auto-does it for you.

Of course there are documentation for this, but I can't go looking right
now. Googling for "change Primary DNS suffix when domain Membership changes"
will help you locate some reference materials.

thanks for the response.

Thas' what I thought.

However, saw something on the net regarding netwok/domain
migration and dc upgrade, the setup of this parameter
seems pretty critical, and just want to get some inside
of it...

Check it. It will do nothing UNLESS you move the machine to a new domain
and then it will do "the right thing."

thanks Herb!

I have bo doubt regarding what this can do.

What I'm interested in knowing is under what
circumstances, I should pay close attention to this
parameter (using default-box checked, or clearing the
box).
 
Primary Domain Suffix tells which domain should be searched in DNS queries,
unless set otherwise by GPO or by manual setting "Append theese DNS
suffixes".

If "Primary Domain Suffix" is the only suffix set, then it will be traversed
in several queries.
Example:
Primary Domain Suffix: compa.comp1.dom
A simple DNS query will first search for the machine in "compa.comp1.dom"
domain,
then in "comp1.dom" domain
then in "dom" domain

Good morning,

Please take a look at articles http://support.microsoft.com/?id=257623 and
http://support.microsoft.com/?id=262376 for a more in-depth explanation of
this setting. It's used to prevent a "disjoint namespace" condition when
upgrading domain controllers from an NT domain to a Windows 2000 domain.

For example, suppose you have an NT domain controller name NTDC1 in a domain
called testdom. You plan to promote NTDC1 to Windows 2000 domain name
testdom.net. If the 'Change primary DNS suffix when domain membership
changes' is left unchecked, the promotion will indicate that NTDC1 belongs
to the testdom (netbios name) domain, not the testdom.net (dns name) domain.
If the setting is checked, the promotion will indicate that NTDC1 belongs to
the testdom.net domain. The first condition is an example of a disjoint
namespace, ie. it belongs to the wrong namespace.

Thank you for your question and have a great day.

thanks.

I think you are right, however, the devolution will stop
at hostname.comp1.dom, with the last two labels.
 
Yes, your right about that.
