Can't Install exchange 2010 in Exchange 2003 environment

This is my current environment.

File and Printer Server, Domain Controller, WInodws 2008 32 bit server
Exchange 2003 Server, Domain Controller, Windows 2003 32 bit server

I want to add a new Exchange 2010 server running on Windows 2008 R2 server. I want to eventually retire the Exchange 2003 server after I move the mailboxes to the Exchange 2010 server. I keep getting an error about an Active Directory Connector has been found and the install can't continue. I can't remove the Active Directory since Exchange will stop working. Can't find what the solution is. Thanks.

The active directory connector service is not installed on my windows 2008 R2 server where I am trying to install Exchange 2010. Where am I supposed to remove it from?

-- Did u verified on 2003 DC ?

-- Try below steps.

Install Support Tools from Windows 2003 CD
Open Microsoft Management Console (mmc)
Add ADSIEdit snap-in
Connect to Configuration Container
Expand Configuration --> Services --> Microsoft Exchange --> Active Directory Connections
Delete ADC under Active Directory Connections
Replicate changes to all Domain Controllers

Won't this render my exchange 2003 server inoperable?

ADC replicates objects from Exchange Server version 5.5 to the Active Directory directory service in a mixed mode Microsoft Exchange environment and is not supported by Exchange 2007 or Exchange 2010.
Exchange 2007 or Exchange 2010 setup requires that all ADC components be removed.

I understand that, but I need my Exchange 2003 to remain operable until I move all of the mailboxes. Won't removing the Active Directory COnnector render it inoperable?

MorasivaCommented:
No.It will not impact the Exchange 2003...

P HurdleAuthor Commented:
Won't that disable it as a domain controller? I have read that if you install exchange 2003 on an domain controller, you cannot remove the domain controller status, it will disable exchange 2003

MorasivaCommented:
Can you please elaborate more ? Are you going to decommission the Domain controller ?.Don't try to remove the DC until you migrate from Exchange 2003 to Exchange 2010?

Simon Butler (Sembee)ConsultantCommented:
The ADC has nothing to do with Exchange 2003. It is a legacy feature for Exchange 5.5.

Look in Add/Remove programs and see if the ADC is listed. If it is, then remove it. This will not have any impact on the operation of Exchange or the operation of the server as a domain controller. It is a connector, nothing else.

Peter HutchisonSenior Network Systems SpecialistCommented:
Simon is correct. All the ADC does is allow Exchange 2000/2003 to import users from the dir.edb database on Exchange 5.5 into Active Directory. The ADC should be uninstalled from any servers and configuration removed from AD. Using ADSIEDIT is best, if the ADC components were already uninstalled but not the config.

Mohammed KhawajaManager - Infrastructure:  Information TechnologyCommented:
ADC was released with initially with Exchange 2000 to ensure Exchange 5.5 and Exchange 2000/2003 servers could co-exist and have common directory.  If you do not have Exchange 5.5 in your environment then there is no harm in removing ADC from your environment.

I removed the ADC from my Exchange 2003 server. The Exchange 2010 install continues to say I have an ADC installed but I can't find one. No components of exchange were ever installed on my F&P server running WIndows 2008 32bit. Not sure where to go from here.

Peter HutchisonSenior Network Systems SpecialistCommented:
You may need to remove any other traces of the ADC from Active Directory configuration. See steps by Morasiva in 3rd comment above.

Now I am getting this during installation. This is very frustrating.

Make sure The Domain and Forest functional levels are set to at least Windows 2003 Server levels.
Also, make sure that the Schema and AD preparation for Exchange have been configured before installing the first Exchange server.

P HurdleAuthor Commented:
Can you please provide some guidance on how to do that?
0
 
Peter HutchisonSenior Network Systems SpecialistCommented:
To check domain level functionality:
Open AD Users and Computers, select the Domain's properties and see the current functionality level, if its still at Windows 2000 level, right click the domain and select 'Raise domain functional level'.

For the forest level, open AD Domains and Trusts, open properties of the Domain name to see forest functional level, use 'Raise Domain Functional level' if its still at Windows 2000 level.

To apply Schema and Domain prep, use Setup.exe from the Exchange 2010 installation files and run
Setup /PrepareSchema
Setup /PrepareDomain

P HurdleAuthor Commented:
Do I run the setup /prepareschema on the exchange server or the domain controller?

P HurdleAuthor Commented:
My Domain Functional Level is now Windows 2003, it was Windows 2000. How do I change the forest functional level which is still at Windows 2000
0
 
P HurdleAuthor Commented:
Got the functional level at 2003 for both now. Still getting the same error after running /prepareschema and /preparead.

Peter HutchisonSenior Network Systems SpecialistCommented:
Also run Setup /PrepareLegacyExchangePermissions before the Setup /SchemaPrep

I ran both to no avail. I continue to get the same message. I can't find what people are saying to look for when I run adsiedit.msc on the domain controller.
