I would just setup each tree's zone as AD Integrated Forest Wide so the zone
will be available on EVERY DC in any domain or tree in the forest. Just set
it and you will see the zone eventually appear by itself on the other DCs
(no need to create it on the other DCs, it will appear automatically).

And no, conditional forwarding, as Herb mentioned, is NOT faster than
hosting the zone locally, matter of fact during issues such as what you've
experienced, which can be attributed to the fact the bandwidth is so slow,
it may cause time-out issues.

Curious, are there any errors in the event viewer concerning AD replication
traffic?
