I am new to Exchange 2003 and am having an issue setting up an Exchange server in a child domain. I have already installed an Exchange server in the root domain and have already run Forest prep in the root domain and domain prep in the child domain. I have made sure that the domain administrator in the child domain is a member of the schema admins and the enterprise admins groups in the root domain. I have done this via a Global group. When I try to install the exchange server in the child domain I get the following error."The component "Microsoft Exchange Messaging and Collaboration Services" cannot be assigned the action "Install" because: - you either do not have the permissions to complete this operation or Active Directory has not replicated all the necessary permissions for the deleted items container. I have looked on other forums but have not been able to find the fix for this problem. Any help would be greatly appreciated. Thanks
