I think this is probably a pretty straightforward problem, but I've failed to get it:
I have domains sam and smc separated by a cisco 2621.  smc has some resources that sam must use.  I've added helper-addresses for the broadcast channel and the pdc of the other side to each of my ports.  I've enabled directed-broadcast and added forward-protocol for the udp 137/138 that pass NetBIOS.  However, I still get the "unable to locate domain controller" when I set up the trust relationship.  Any ideas?

Here's the Qbase article for the whole story:

Port 135 for RPC calls should be opened as well.  We just set up a similar network last week but didn't need 135 for our purpose.

Opening these ports will stuff up your browsing :

+if you use Cisco's IP helper, look at :

You need the 139 nbsession port to establish a session to create the trust account.

Have you tried adding the details of the domain controller into the LMHOSTS files, this helps your local machines easily resolve the NETBIOS name.
Provided your machines have routes in place for the IP network of the domain controller then it can route for the IP in the usual way.

Not the most "spangly" way of doing things but should work for you.

I find that an interesting accepted answer because without port 139 you would be unable to create a trust.
