Which, in order words, means that SEPARATE FOREST does not in itself protect 
you from an internal "clever domain admin" in any of the domains/forest. Unless 
you go through the troubles SID filtering, SA, and other ACLing. And, even with 
all that in place, "a clever domain admin" will still be hard to keep out, 
especially if the admin is clever, malicious and determined at the same time. 
This goes to show that you don't want to have any "clever domain admin" that 
you can not completely trust in any part of your infrastructure. This, to me, 
is your most basic and effective protection.

Hi David,

In addition to SID filtering, you can protect a trust between domains in two 
forests (either a forest trust or an external trust) by using selective 
authentication (SA). SA is sometimes called authentication firewall, and the 
idea is that only listed users can access only listed servers across the trust 
(in addition to traditional share and NTFS permissions).

If the new domain creates a new forest, its domain admins are not subject to 
the Enterprise Admins of the existing forest. This may or may not be of 
relevance to you.

I'm not sure if I understand your last question, but a forest trust is only 
possible, if both forest are on the WS2003 FFL.

Yours, Sakari
