NT 4.0 Trust Relationship Vulnerabilities

[susecam]

I'm wondering if anyone could help me with some information about NT 4.0 trusts. I am specifically trying to come up with a list reasons why I would not want to trust another NT 4.0 domain (from a security perspective). I need specifics like attacks that can be performed or vulnerabilities that are introduced by creating an NT trust.

All comments are appreciated
