I've heard the same thing - with AD it doesn't make any sense to have a site that doesn't
have a DC in it - sites are used for
replication and if there's nothing to replicate to in a site then
why would you create an AD site? But with SMS, you can define
SMS Site Boundaries and Roaming Boundaries
with either subnets or AD
Sites... guess which is easier to do for the SMS
admin? So if the AD admins create a site for every area you'll have a DP in, then it makes it easy to set up
boundaries. That is, it's easy if you trust that they are putting the right subnets
in the right AD sites, and you get the right AD sites in the right SMS
assignment boxes and spell them
correctly. Barring all that, you could just add the subnets in the
appropriate places in SMS and ignore the AD sites.

Sites are a collection of "Well Connected"
subnets. That said, one persons definition of "well connected"
can be completely different from another's. It really depends upon the
bandwidth and network utilization between locations on your network. On
some site designs I've set every location to be a site no matter what the
bandwidth while on others I have groups locations together into a single site
where bandwidth was "good enough" and the load put onto the network
was deemed to be minimal. So, the answer is, it depends! I
would think that adding SMS would make you rethink how you have grouped your
sites to optimize the use of the SMS distribution points. Too many users
hitting the distribution points will put a significant load on the location to
location links and that would move you towards defining a location to be in a
separate site.
Just my $.02. Coming out of lurking mode. Great
list. Thanks for being here.

Site Configurations and SMS2003
All:
I know that this is
somewhat off topic (SMS) but I had a recent conversation with some folks in
regards to AD and SMS 2003. We are looking at possibly deploying SMS 2003 and
looking at some deployment scenarios. Anyway the conversation turn to the
AD sites and what is the best configuration for sites in an organization.
Briefly we have a highly
connected backbone with DCs spread around key nodes on this backbone to support
the geographical locations spurred off of this backbone. We developed our
AD sites around these nodes (5 geo locations, 5 AD sites) with all the
"downstream" geographic locations for each DC being rolled into the
site.
It was recommend that we make
each geographic location that are rolled up to the main sites we have now a
separate site in AD irregardless if this geographic location has DC or
not. Site connectors would be built between those sites that have
DCs and for those sites that don't have DCs, we'd have to go in and hack
the _kerberos._tcp.<site name>._sites
and the _ldap._tcp.<site
name>._sites SRV records so that
they would refer to the correct DC.
I'm still trying to grasp
the nuances of sites in AD but this seemed to be an usual approach to sites in
AD. Granted that SMS 2003 does bring some twists to the picture as a
client will need to identify a distribution point from it's AD site. We
have over 200 individual geographic sites with approx 180 software distribution
boxes that we'd make distribution points. That would translate to 180 AD
sites (sites mapped to distribution points). My basic understanding of
sites is that the should be built around DCs.
This is a
simply summary of what was discussed but I
was wondering if there
was some opinions one way or another over the best way to approach sites in
AD. Obviously each case is different but wanted to capture folks
thoughts.
