My understanding (flawed it might be) considering the original question and design you suggested. Says you want a separate Tree, the two branches of this tree if you will can be on different subnets one for ourcompany.org and another for theircompany.org, you do not get this with the Child domain model. You only get the seperation you suggested with the separate Tree model, or a completely separate forest. But you can't go the Forest route, well unless you went to Windows 2003 then you could do a level 3 Federated Forest to share the GAL, Calendar excetra between forests. But that is outside of what you asked. Yes you can have these two trees on separate ip address or segments if you want to do that.
A Forest is one or more Trees. The trees in a forest do not share a contiguous name space. However, the trees in a forest share a common schema and global catalog. Although two orgainizations do not share a common name space, adding the new Active Directory domain as a new tree in an existing Forest allows the two orgainizations to share resources and administrative Functions. In this model I do belive you can share a single Exchange 2000 Server and maintain the structure as you asked. -----Original Message----- From: Ray Beckwith [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 03, 2003 12:06 PM To: Exchange Discussions Subject: RE: Exchange and AD Question In either the child-domain or new tree scenario, is there a need to separate them onto a subnet or can they just be assigned IP addresses from our existing class C block?

(Note the subtle butt-kissing) Situation: Single domain forest with single Exchange Server and total 4 DC. About 85 Employees. Class C IP block with fixed IP addresses for all. We are in the process of starting up a new venture company and want to keep them relatively separate from our main organization so as they grow, they can be easily separated if so chosen. We have our web presence under ourcompany.org and have reserved a domain theircompany.com for the new company's web presence. We have also set up recipient policies in Exchange to receive email sent to theircompany.com for the first couple users we have set up in our domain. Question. What would be the best way to set up this new company in our AD organization to meet the requirements of easy separation in the future, while allowing us to continue serving them with our single Exchange server and with minimal additional expense and complexity. We have been looking into the possibility of setting up a child domain for them so that they can have separate security and domain suffix but are unsure if we can do this without adding a subnet or some other complexity. I appreciate any opinions or recommendations from the wise ones of the list (more butt-kissing). Thanks...
