Try to run setup with /DomainController parameter to specify the additional DC W2K3 R2 SP2 as the domain controller http://technet.microsoft.com/en-us/library/bb125224.aspx Deli

Hello,I have tried that step with no luck still produces that error message!How can the setup not see that the domain controller isn't running SP2?ThanksBen

Maybe you should read this guide: http://www.msexchange.org/tutorials/Installing-Exchange-2007-Small-Business-Server-2003-domain-Part1.html http://www.msexchange.org/tutorials/Installing-Exchange-2007-Small-Business-Server-2003-domain-Part2.html Deli

Hello,Managed to fix the above problem but am not getting another error when I try to install a hub transport role.http://www.circlestech.com/technet/HubTransportError.jpgAny ideas?ThanksBen

Hello,Managed to fix the above issue by changing a OU. I'm now getting another error relating to the installation of the Hub Transport Role!http://www.circlestech.com/technet/HubTransportError.jpgHow do I fix this error I'm getting?Thanks Ben

The error doesn't say much does it? Maybe you can find more info about the error in this log C:\ExchangeSetupLogs\ExchangeSetup.log Deli

Hello,I've uploaded the log http://www.circlestech.com/technet/ExchangeSetup.logThanksBen

Almost at the bottom of the log you can find this: Compiling assembly C:\Program Files\Microsoft\Exchange Server\bin\Microsoft.Exchange.Management.SnapIn.Esm.dll ...Error compiling C:\Program Files\Microsoft\Exchange Server\bin\Microsoft.Exchange.Management.SnapIn.Esm.dll: Strong name validation failed. (Exception from HRESULT: 0x8013141A) Maybe there is something wrong with your installation media? Or you can try to download the Exchange 2007 Rollup 4 and install before installing HUB transport http://support.microsoft.com/kb/940006 Deli

You try to verify the signature of the Assembly dll with sn.exe This is a tool from Visual Studio sn.exe -vf Microsoft.Exchange.Management.SnapIn.Esm.dll Otherwise I would try with another installation media. Deli
