Re: Do i need to create a site in AD?

Hi Thanks very much for the help with this. If iam going ot create the other
site, in AD, do i need to configure my network id and subnet for the remote
site in AD, and then do the same thing for the default original site in AD?
right now the subnet and network id's are not defined

Thanks

Hello all

All my AD domain controllers are running Windows 2003 sp1, i have two
domains in the AD forest. Right now there is only one site in the AD
forest,
and all domains are in this site. We now are connecting a remote site over
a
site to site VPN to our main site. We are going to place an DC/GC in this
remote site.

The moment you place a DC in a "remote location" it almost
certainly should be made a SITE.

If it looks like a WAN it is almost always a different site (if it
has DCs or other site aware services), and if it looks like a
LAN it is almost always the same site (but there are strange
exceptions that usually only affect large companies.)

The remotes sites ip id is 10.60.50.x/24 the main sites network
id is 10.20.0.x/24 there is also an Exchange 2003 sp2 server at the main
site. My question is based on the infromation that i have outlined in this
post do i need to create another site in AD for the remote physicall site
that we have? and if so do i need to create a site link, and site link
cost?

Yes. The instant you creat a Site you need a "Site Link" between
it and all existing sites -- you must have at least on "Site Link" between
each site or set of sites so there are no isolated islands of disjoint
sites.

As to the Site Link needing "Cost, Schedule, and Frequency" you must
configure these options but with only two sites the defaults will ALWAYS
work but may not be ideal.

Cost doesn't matter until you have MULTIPLE pathways through different
sites (which can't happen with 2 sites).

Schedule defaults to 24 hours/7 days a week which suits most people but
may not be your ideal setup.

Frequency defaults to 3 hours which is reasonable for most people but is
also the most common thing to change for a small forest.


There are 16 machines on the remote network, and right now they must go
over
the site to site for any and all resources on the netwok. We were thinking
that we could speed up access to Exchane and other network resources by
placing a DC/GC and then creating a logical site in AD.

With a single domain forest you can always make ever DC a GC, and with
a SMALL FOREST this is usally fine as well so in your case it might
make sense to make every DC a GC.

Exchange needs the GC specifically; each site needs a GC generally.

Having the DC (and GC) local will speed up things and usually reduce
WAN usage (in exchange for the extra replication which is usually small
or can be done at night.)

What about DNS and WINS?

Most "locations" with a DC need at least the DNS and frequently the
WINS Server, although for NetBIOS the node type can be MIXED and
is generally the better choice for those with "hundreds of sites".

You almost certainly need NetBIOS to resolve even with all modern
machines, and IF you need NetBIOS and have more than one SUBNET
for IP you need WINS Server(s which replicate.)

Every machine needs to be a WINS 'client' on its NIC->IP properties
(including the DCs and even the WINS Server itself.)
