Got a hostname - can't resolve it.

On my PC, yes. On the DCs? Don't know.

Oodles of sites, can't really tell that there's one setup for the other
domain. What should I be looking for here?

that would definitely be out of the question. I can run a port query from
PCs and member servers.

I'll see if they can create an account for me to test with.

They're currently allowing perhaps 7 DCs on each domain to contact one
another. The FW guys say that there's no port restrictions, they're just
allowing IPs to connect to one another.

One enterprise group controls our DCs and FWs, another enterprise controls
the other DCs; FWs on the other domain are controlled locally. Everyone
says that their part is configured correctly (of course). Seems like there
should be a way to set up a bridgehead or two on each domain, and then just
allow the bridgeheads to talk through the firewalls. One enterprise AD guy
believes that we need to configure the firewalls with ACLs for all of the
DCs (hundreds) on both domains (so hundreds X2); I'm hoping there's a more
succinct way.
