In Best Practices v2.6 I am getting the follow message: Updated EXCDO.DLL file detected EXCDO.DLL file version on the server asnmail.autosoldnow.local is more recent than the installed version of Exchange. This is probably a hotfix. Installed file version 6.5.7620.29 It has a yellow flag beside it, when I check out what MS's technet says all I get are links to Exchange 2000 or 2003 downloads site. Is this something I should worry about? Oh I almost forgot I have Exchange 2003 SP2 installed which sits on top of Windows 2003 Server SE AD :( Regards, Andrew ________________________________ From: exchangelist-bounce@xxxxxxxxxxxxx on behalf of Rahul Kochhar Sent: Sat 20/05/2006 10:50 AM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: Exchange 2000 to 2003 migration In short-n-sweet... First upgrade your Exchange to 2003 from 2000 and then upgrade the AD to Windows 2003 Forest Level. Upgrading Exchange would be as simple as putting the CD and following the Exchange Deployment Tool to upgrade. For Windows 2003 upgrade you will need to run ADPREP with a /FORESTPREP and /DOMAINPREP option and then upgrade the DC. Internet and Microsoft Support Site will get you more detailed answers on that.
