Installing Exchange 2003 in 2008 R2 Domain /forestprep compatibility issues
Posted on 2010-11-24
We have setup a new Windows 2008 R2 Domain with Windows 2008 R2 Domain Controllers. However I am trying to install Exchange 2003 in this domain. I realise that I must install Exchange 2003 on Server 2003, that is fine.
However, when I attempt to run the Exchange 2003 Setup\I386\Setup.exe /forestprep and /domainprep on the Windows 2008 R2 AD server, it does work.
I receive the Program Compatibility Assistant error "This program is blocked due to compatibility issues". There is no way to ignore this error and Continue. The only options are Cancel or Check for sulutions online.
How can I prepare my 2008 R2 domain for Exchange 2003? Do I need to disable the Compatibility Assistant? If so, how? Do I even need to prepare the Domain?
Thanks for your help!
