- Recommended that
you move up to SP4 on W2k DC's
- When you decomm
the
DC in site B (using DCPROMO) enure that FRS member objects is gone
too
- DC in Site A will
automatically cover Site B (without DC) by registering the required SRV in
DNS (provided that you have not disabled auto-site coverage AND provided
that B and A has the lowest costings than other sites)
- Auto-site
coverage
algorithm will select the candidate DC's based on GC's/Costs etc...there
are
articles on Auto-Site coverage on MS website...

My understanding of
sites is that each site must have at least one DC. If my understanding
is correct, your planned action to decomm the Site B DC would lead to the
removal of Site B and its incorporation into Site A. As long as the
computers in Site B have the proper DNS server addresses, you should have no
problem (note the operative word 'should').

Subject: [ActiveDir] DNS and site
coverage behaviour
I
am about to investigate and test DNS site coverage and would like to seek
the
views and opinions of others.
Scenario:
W2k DCs
(SP3)
Multiple domains - all w2k
native
Location1 has 2 buildings,
currently each building being represented by a separate site. Let's call
them
siteA and siteB.
Currently, each of these 2 sites
has a DC installed locally.
SiteB has a site link with siteA
(cost 10)
SiteB has a site link to siteC
[at
some other location] (cost 100)
Proposal and
requirements:
Decomm the DC in siteB and
ensure
that the DC in siteA provides DNS coverage to users in siteB [I won't
explain
my reasoning for the decomm - that would detract from my main point :)
]
Questions:
Will the
DC in siteA need to be configured such that it auto covers DNS wrt siteB
(registry change)?
Or
Will
that
DC in siteA automatically cover for siteB in DNS, given that siteA has the
lowest cost link to siteB?
I
had always assumed the latter to be true, but this view has been challenged
and the former was suggested as necessary, instead :)
Any offers?
Thanks,
neil
