Re: One Way TRUST Through Firewall problem

It sounds as though you may have an issue with the ephemeral
ports used by RPC being blocked by the firewall. It is possible
to constrain RPC to using only a known range of ports, but before
you go down that road you ought verify whether this is the problem
(such as by packet examination in a capture).

Hi

If there is a better group for this then let me know..

I have a one way trust domain setup between two windows 2003 forests with
a
firewall between the DC's. The trust works ok and validates from both
ends.

When I come to add a user from the trusted domain a group in the trusting
domain (or assign file permissions to a user in the trusted domain), I
can't
browse the foreign domains OU structure and can't find any users in the
domain. The domain is shown in the locations dialog but when you click
on
it, there's a long delay then it just doesn't expand to anything.

I have opened LDAP (389) and all the suggested trust ports. Nothing
suspicious appears to be being blocked on the firewall other than a few
ports
in the 18XX TCP range.
