Dear All,according to microsoft, http://technet.microsoft.com/en-us/library/aa996719.aspx"For the release to manufacturing (RTM) version of Exchange2007, in each domain (including child domains) where you have the Exchange Enterprise Servers and Exchange Domain Servers groups and therefore must run Setup /PrepareLegacyExchangePermissions, you must have at least one domain controller that is running WindowsServer2003 SP1 or a later version."In our child domain, we still have some are window 2000 domain. But we are run the setup /pl on root domain (no exchange server), it fails, and said the resaon is some of domain dont have windows 2003 dc.Is it true that, we cannot deploy 2007 until all domain have at least 1 dc in running windows 2003?Thanks a lot.

Hi, Yes that is true. That was the criteria till Exchange 2007 RTM, but it changed in Exchange 2007 SP1. In SP1, you required at least one Windows 2003 SP1 DC/GC in the domain where you are running setup and you can install Windows 2003 SP1 DC/GC in other domain before you install Exchange 2007 in that domain. Here is an update from Exchange Team... A setup prerequisite change in Exchange 2007 SP1 I hope this helps...

We already use the disc Exchange 2007 SP1, but still failXXX.com is root domain, dont have exchange server, domain function level is windows 2000 mix.For Example. we have 2 child domain. HongKong and JapanHongKong domain function level is windows2000 native ,have window 2003 dc and exchange 2003we just want to install exchange 2007 in this domain first.Japan domain is only window 2000 dc and exchange 2000The error message is below.

Hello, You can ignore below two warnings if you are sure about Windows 2003 SP1 in a domain where you are installing Exchange 2007 SP1. Cannot find the Recipient Update Service responsible for domain 'DC=XXX,DC=com'.

Below checklist would be helpful. Planning Checklist You may also run ExBPA with Exchange 2007 Readiness Check before installation and check if any errors are there.

Dear Amit, After upgrade all Exchange 2003 SP2 and still fail after run "setup /pl" have same error Cannot find at least one domain controller running Windows Server 2003 Serv ice Pack 1 or later in domain 'DC=XXXX,DC=Company,DC=com'. This could be the resu lt of moving domain controller objects in Active Directory. Check that at least one domain controller running Windows Server 2003 Service Pack 1 or later is loc ated in the 'Domain Controllers' organizational unit (OU) and rerun setup. Active Directory root domain 'DC=company,DC=com' is in mixed mode. To install Exchange Server 2007, this domain must be Windows 2000 native mode or above. The Exchange Server Setup operation did not complete. For more information, visi t http://support.microsoft.com and enter the Error ID. Exchange Server setup encountered an error. In the company.com , we dont have any exchange server in here, According to Microsoft http://technet.microsoft.com/en-us/library/bb288907(EXCHG.80).aspx The Following commands to be completed before installing the first Exchange 2007 server. 1. Setup /PrepareLegacyExchangePermissions 2. Setup /PrepareSchema 3. setup /PrepareAD 4. Setup /PrepareDomain I am thinking can i skip run Setup /PrepareLegacyExchangePermissions , it seems only require on exchange 2007 RTM not SP1 Any ideas. Thanks

Make sure that you have at least one DC running on Windows 2003 SP1 or later in HongKong domain where you are installing Exchange 2007 & xxx.com is fine with Windows 2000 DCs. You need to raise the domain functional level from 2000 mixed to 2000 native to install Exchange 2007, here is the Planning Checklist & a guide to Raise the domain functional level.

Dear Amit, Thanks.We will try to upgrade xxx.com to Windows 2000 native mode and try again. Can i use setup pl/hk.xxx.com to bypass the error becasue i just want to install exchange 2007 on Hong Kong Domain first. Will it affect all exchange organization?

Not to add more confusion to this,as I'm also getting same message that the DC must be at least W2K3 SP1 but I just wanted to know if anyone knows if having a Windows Server 2008 as the DC instead is suppose to meet the requirements. I've setup a Windows 2000 Forest with 2K DC's and Exchange 2000 and trying to introduce Exchange 2007. I've updated the Schema (Inetorgperson kit), installed and added a2008Server as a Domain Controllerand made it the Operations Master but still says the original W2K Domain Controller which was the Operations Mastermust be W2K3 SP1. Have I miss something somewhere?

Hi , btw, where do i run the below commands : 1. Setup /PrepareLegacyExchangePermissions 2. Setup /PrepareSchema 3. setup /PrepareAD 4. Setup /PrepareDomain Is it in the main AD or the domain which has the exchange 2003 installed or in my system where i plan to install exchange 2k7. Sorry to ask the basics here.. But I really requires this as i am stuck with the e2k7 installation setup. Thanks to ALL. Regards , John

Hi John Please check this link:http://www.msexchange.org/tutorials/Installing-Exchange-2007-Part1.html

Sry for bringing up this rather old thread but I've had the same issue. I removed all win2003 DC's and replaced them with win2008R2 DC's.(half year ago) Then I tried to migrate from exch2003 -> 2007 but I encountered the same error as the person above. Now I installed a win 2003 DC and I have passed these steps. But I wonder, when everything is migrated from exch2003->2007 and I uninstalled the exch2003 from our domain, can I remove the WIN2003 DC and proceed with our new 2008R2 DC's? Exch2007 will be installed on a WIN2008 SP2 64BIT. regards, murda

Hi, The exchange 2007 install worked after I installed a 2003DC. Can I remove this DC again after migration (I have 3 2008R2 DC's) grtz.
