I'm trying to install Exchange 2007 on a brand new installation of Windows Server 2008 x64 Standard.
Mailserver is just running Exchange, there is another (2008x64std) server as domain controller running Active Directory in server 2008-mode and a third server running sql.
I managed to get Exchange running on the mailserver sometime early this week but when i started messing around with OWA/OMA i broke something and ended up reinstalling the mailserver. The AD had already been infested with exchange-stuff so i reinstalled the domain controller too just to be safe.
Now the funny thing, i cannot install Exchange again. These are two completely fresh server installations but i still get an error saying
quote:

This is both when i use the graphical view and when i use setup.com /
Google gives me nothing, i've already reinstalled the servers twice today and they have to be deployed next week. Going insane here...

I think i have a solution in hand, just wanted to read a bit in-depth into your Exchange Setup logs to verify if the solution which i have is for the same issue.

Can you check do you have KB 926776 as a hotfix ? Also, it seems you have not run the pre-req commands.
/prepareschema
/prepareAD
Have a look at what setup logs mention.
[2008-07-10 18:36:05] [0] Schema Update Required Status : 'True'. [2008-07-10 18:36:05] [0] Organization Configuration Update Required Status : 'True'. [2008-07-10 18:36:05] [0] Domain Configuration Update Required Status : 'True'

I do not have that KB installed, all mine start with 94 or 95
/prepareschema gives me the same errors as before. I'm downloading the hotfix and trying it now
**edit
Unable to install the hotfix, "the program to be updated may be missing, or the upgrade patch may update a different version of the program".
I cannot download .net 2.0 since it's already installed by the operating system, and the .net 2.0 sp1 isn't supported on "vista operating systems"

Read the last column which refers to the .Net Framework update
sadly i get the same error with that update, ""the program to be updated may be missing, or the upgrade patch may update a different version of the program"."
I'm just going to get a good nights sleep, reinstall the server (or all of them) in the morning and try again. i just hope i can put this out of my head for a few hours now

You're not going to believe this.
Coming in to work 30 minutes earlier today i tried running the setup again, same errors.
I then put in another media (the action-pack disc with exchange 2007 sp1) and it works, i now get the message that the AD isn't prepared yet and that i should install other features before installing Exchange.
Trying the original setup once more gave me the errors i got yesterday.
The original setup comes from a downloaded from microsoft.com, SW_DVD9_NTRL_Exchange_Svr_Ent_2007w_SP1_X64_English_STD_ENT_( removed, is this key unique for us? ).ISO
Burned on a dvd9 with verification and redownloaded after some dlls was unreadable.
So basically i have narrowed the problem down to the media i tried installing from
1) the .iso from microsoft.com is faulty or something went wrong in the transfer and the downloadmanager never checks crc
OR
2) files were unpacked to domaincontroller and transfered over the network to the mailserver and somehow got flagged in windows as insecure.
At $100/hour, spending 16+ hours trying to install this d*mn thing is not what the customer is going to want to pay for..

Trust me the installation had caused major problems for Exchange 2007. There were very very few instances of such sort at Exchange 2007 as per my sources.
Also, there has been only "one" instance which was solved by re-downloading the DVD media. Reason why i was insisting on getting that .Net fixed was the hex code what you pointed out.
Well, im happy atleast the downloading the new media got issue solved.

Thank you for all your input and suggestions, i now have a fully working Exchange 2007 installation thanks to the downloaded version of Exchange SP1
Also following msexchange.org - installing exchange 2007 helped a great deal.
