Well Michael, your scenario involves many Q&A... infraestructure (physical and logical), messaging, administration (central or distributed), domains, etc. etc. and a lot of planning... The big questions is where do you want to be tomorrow? Would you like a single AD forest with a single domain and 7 sites, or 7 domains, or x forests with or with out relation trusts? That depends on your infraestructure (type and speed of links, etc) and political and administration issues. The same goes with your messaging environment... You can migrate AD from one forest to another, but it isn't a simple task, there are a lot of considerations to take into account, and that depends on the complexity of your infraestructure.

Do you know of any Q articles or whitepapers that address this type of mixed environment? Also, can you provide me any feedback on the following scenario? The Department of Labor has 7 agencies, all on their own separate physical networks. Each of these agencies has their own messaging platform. Four of them are already on Exchange 5.5, two of them on GroupWise, and one of them on Unix SendMail. We are presently trying to design a 5.5 solution that includes creating a single DOL organization and migrating each of the Agencies to the Exchange Organization. One of these Agencies has recently reported to us that they are 3/4 of the way through implementing Windows 2000 with AD (Native Mode) Single Forest. I'm trying to get a handle on what concerns and technical solutions will be required with regards to this one Agency. Everyone else will be on NT 4.0 domains. If an Agency here at DOL has already implemented a Windows 2000 / Active Directory (NM) within it's own Forest, is it possible to migrate that Forest into a new DOL Forest at a later date. How will an Agency already on Windows 2000 with AD migrate to the new DOL.gov? Are there any complications? Does it matter whether this Agencies W2K/AD is in native or mixed mode? Thanks in advance Julio. I appreciate your insight and support! Regards, Michael V.

But you will experience problems if you install Exchange 5.5 on a DC, both use LDAP port 389 for directory lookups. So the best solution is to install Exchange on a Member Server or change the port it uses if you have no alternatives to install it on a DC. Julio E.
