That should be "GCs cannot replicate
partitions they don't own...." right?

Is
it a GC? If so, then yes, that's to be expected. You may have *thought* that
you gave it only one replication partner, but if you're seeing additional
connection objects, then it has more than one replication partner. When
planning replication, you must be aware of every partition that the DCs in a
site are hosting. If you don't want that remote DC to have connection objects
from all of those other DCs, you're probably going to need to set up
connection objects for preferred DCs for it to use for replication of
partition data. If it's a GC, and if you have a GC that is a DC for the same
domain in another site, that would be a good choice to set as a replication
partner, because they would be able to replicate all of their partitions (GCs
can replicate partitions they don't own to other GCs).

It's a Windows 2000 native domain, we're about 4
upgrades from having all Win2k3 DCs and from what I've read, that should
help a lot with replication.
Automatic site link bridging isnt enabled, and we have
0 site link bridges.
We're a worldwide company with 3 main hubs, but it is a
mesh network in design (MPLS).
I guess i'm mainly confused because the DC at the slow
bandwidth site in question only has one replication partner, yet we see
connections to it from a large number of our DCs on a regular basis.
Is this normal?
Intervals vary by company, domain structure, network topology and
latency tolerances. That said, there is nothing inherently wrong with the
replication parameters you list below. Are they the best parameters for your
environment? That depends. Is this a Windows 2000 environment? Is automatic
site link bridging enabled? There's a lot to consider in determining how to
set site link properties; what you've listed below won't really be enough
for anybody to give you any kind of realistic advice.
(sorry)

We have about 80 AD sites with DCs. All sites are set for a
cost of 100 on the site to site replication, and a replication interval of
15 minutes. I'm presuming this is probably not a good thing.
One slow bandwidth site is complaining that their DC is talking to
every DC in the domain.
What is everyone else using as a replication interval for
inter-site replication?
