Exch2K replication w/ Win2K SBS Servers

If I understand you correctly, you have 2 separate domains based on SBS2000 (since you can't have more than 1 SBS server in an organization) and you want the Exchange installations on each to replicate with each other.

If this is the case, the answer is SBS limitations will not let you do this. Replication only takes place between AD (or Exchange) servers within the same forest.

From the Technical FAQ on the Microsoft SBS Home Page (http://www.microsoft.com/sbserver/ techinfo/administration/2000/TechFAQ.asp) (remove any spaces from the above URL):

"Small Business Server must be set up as the root domain controller of a Microsoft Active Directory? forest, which prevents Small Business Server from serving as a corporate branch office or divisional server of a larger organization with an existing Active Directory or Microsoft Windows NT? 4.0?based domain infrastructure. Moreover, trusts with other Active Directory forests are not allowed, which means that a user will not be able to set up an explicit trust (for example, in the style of Windows NT 4.0) with another domain. And Microsoft Exchange Server in Small Business Server is restricted from being part of a larger Exchange Server organization."
