We are attempting to install Exchange 2010 on a 2008 R2 server with an Exchange server 2003 on Server 2003. After running pre-deployment analizer it reports the following.
 Server nirvana.mydomain.local is running Exchange Server 2003, but has not been upgraded to Service Pack 2 or later. Exchange Server 2010 installation will be blocked until this server is upgraded.

We have reinstalled SP2 twice now but still get the same result. There must be a registry key not being updated by if so which one.
Thanks for your help in advance.
Regards
Dave

I may be trivial, but the SP2 you installed is the Exchange 2003 SP2 or just the Windows 2003 SP2 ? Is not the same thing.
Exchenge 2003 SP2 can be found here:

Yes, trivial. We are an IT support company and have spent some 2 days looking for the answer.

If we run the install for Exchange 2010 when we select the connector (the 2003 server) it shows Version 6.5 (Build 7623.0: Service Pack 2). So when it performs the prerequisites tests it then fails with the error indicating the 2003 server is not Service Pack 2, strange as it has already seen it as haqving SP2 installed.

So looks like there's some kind of corruption on the AD metadata. You'll hardly find an answer to this question on the Internet.
As a last try, install all the post SP2 hotfixes for both Windows and Exchange and try again. Otherwise, for metadata problems, I always suggest to open a Microsoft ticket. Sometimes is cheaper than wasting time. If you make mistakes in editing the metadata, you can destroy you AD.

Depends on what 2010 install is looking for. We have checked AD using ADSIEdit and found nothing. I agree there is an entry somewhare it looks at but this has to be something  other than what it finds when adding the connector, as this is the correct version.

Exchange setup thinks there is no SP2 on Exchange 2003
so first you should check in every possible way if SP2 status for your Exchange 2003 box has been put all places.
This will help you determinie that on every level.

This appears only to tell us if we have a limited version of exchange or not. In our case we are using 2003 enterprise.

We realise that there has got to be an incorrect entry in AD or the registry but we are unaware of where we can locate all the entries necessary. The article you linked to unfortunately does not give us this information.

The version is 6.57623.0, which is what the 2010 install sees as the connector version during the initial part of the installation as mentioned above.

Ah..
You must install SP2 on your Windows 2003 Server, not Exchange 2003.

SP2 is installed to the server. 2010 readiness tool reports the following:

 Server nirvana.mydomain.local is running Exchange Server 2003, but has not been upgraded to Service Pack 2 or later. Exchange Server 2010 installation will be blocked until this server is upgraded

For everyones information we have now resolved this issue. It appears there are 2 Versions of Excxhange SP2,  Build 7623.0 is the one we had downloaded from the MS site but is the incorrect build version. We eventually found build 7638.2 on the Technet site (should have used this one first but hey!!) Not sure where else it can be downloaded for others who do not have access to Technet.

Thanks everyone for your input though.

It was a SP2 issue but not that transparent.

Just to clarify. You can download SPs from Technet without the needing of a Technet subscription. My very first answer had a link to the Technet version of the SP2 (Build 7638.2) that's public (I no longer have a Technet subscription and I can download it). Incidentally my answer was not so trivial. I didn't know that MS Downloads was still posting an old buld of the SP2, I always get SPs from Technet. Technet (subscribed or not) should be the primary source for every technical matter.
In my opinion the accepted solution should be your own (ID: 33792679). This is the only one that answers the question.

It would be more usefull if MS posted Build numbers on the download screens allowing users the option to only download the version they want rather than a very time consumming process of download and install. Thanks for all the input.
