Root domain is place holder only, all Exchange servers and mbx accounts reside in Child domain. ie NO recipient RUS configured for the root domain. Just wanted to verify that we are good to go forward with Server install into Child domain. The AD team ran the following with no Errors/Warnings. /PrepareLegacyExchangePermissions:adtest.ad.lab /PrepareSchema /PrepareAD When performing /preparedomain:adtest.ad.lab theyreceive the following warning [1/9/2007 1:16:24 PM] [1] Beginning processing.[1/9/2007 1:16:47 PM] [1] [WARNING] Cannot find the Recipient Update Service responsible for domain 'DC=ad,DC=lab'.

We have no Root RUS so I'm not too concerned with this Warning, do you Concur? can we move forward with Server installations? 2). PrepareAD seems to be required and also seems to prepare the Local Root Domain. Did we Prep correctly or are we missing something here?

Since Exchange Server 2007 is not use RUS Object anymore.Exchange 2007 has a new predefined Exchange Administrator role called Exchange Recipient Administrators. This role contains permissions to manage the e-mail attributes of all users. After you run this command, you must wait for the permissions to replicate across your Exchange organization before continuing to the next step. If the permissions have not replicated, the Recipient Update Service on your Exchange Server 2003 or Exchange 2000 Server computers could fail. The amount of time that replication takes depends on your Active Directory site topology When you first run prepareAD it'll include prepareDomain in local domain.If you have any other domain which want to install exchange server 2007 you need run prepareDomain in local domain. Run once in Root Domain: Setup/pl Setup/ps Setup/PrepareAD Run once in every domain which want to install Exchagne Server 2007 Setup/prepareDomain Or you can run Setup/prepareAllDomain for all AD Domain.

Thanks Jammy, that helps. Yes, prepareAD does need to run in the Root and prepares that local domain. This seems to be a little different thanEx03, our Root domain is a place holder only and Domain Prep was only ran on the child. We obtained further information from the AD team, they say that preparedomain:child domain only Warn'd about the Root RUS, and then completed successfully.Since we have no Root RUS, I'm not surprised a Root RUS test would fail. We are going to move forward with Ex07 Server installation.

Glad the information is useful for you. You can follow below step to check PrepareAD and PrepareDomain is successfully . To verify PrepareAD completed successfully, make sure that there is a new organizational unit (OU) in the root domain called Microsoft Exchange Security Groups. This OU should contain the following new Exchange Universal Security Groups: Exchange Organization Administrators Exchange Recipient Administrators Exchange View-Only Administrators Exchange Servers ExchangeLegacyInterop To verify PrepareAD completed successfully have a new global group in the Microsoft Exchange System Objects container called Exchange Install Domain Servers The Exchange2007 Domain Servers group is a member of the Exchange Servers USG in the root domain. On each domain controller in a domain in which you will install Exchange 2007, the Exchange Servers USG has permissions on the Domain Controller Security Policy\Local Policies\User Rights Assignment\Manage Auditing and Security Log policy
