>Hi All:
>I´ll set up two W2K servers domains. The first domain (D1) will be the domain controller master role which will holds the user accounts in an Active Directory scheme. The second domain (D2) will hola the database engine. The users authenticate against D1 and then access the database in D2. The question is: How should I setup the user accounts en D1 in order to get access in D2.

Why do you need two domains? Just set up a single domain with D1 as the PDC, and make D2 a member server of the domain admisinstered by D1.
