Secure.mdw and users on different domain

[Alex]

I have a workgrp file and a secure db on one domain and a
script that makes shortcut to this DB and wrkgrp file for
each user. Users on the residing server runs the script
and their short cut runs fine other domain do not. The two
domain servers are trusted but they get a message saying
that access cannot open the file because the file is on an
untrusted domain.

Help anyone!
