MS Exchange Forest Functional Level Error

I am trying to install MS Exchange 2010. The only 2 DCs in the domain are Windows 2008 R2 The Forest Functional Level are Windows 2008 on both, but every time I run the Exchange installation and it goes through the pre checks it always comes back with "Forest Funtional Level is not Windows 2003 native or later" and that is simply not the case. It always also gives an error that "a reboot from a previous installation is pending. Please restart the system and rerun setup" and that also in not true. It says that even after just rebooting and then running the installation (exchange). Can anyone please shed some light on this dumb issue. The server that is being used for exchange is brand new, with Server 2008 R2 SP1 with all available updates.

Thanks in advance.

Look here:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager
 \PendingFileRenameOperations

See if there is anything listed. If there is, remove them.
Then reboot the server and run Windows Update again to ensure everything has installed correctly.

For the forest issue, verify the forest is what you expect. Open adsiedit.msc, look at Default Naming COntext. RIght click on the domain and choose Properties.
Look for the value of MSDS-Behaviour-Version - it should be 3 for Windows 2008 or 4 for Windows 2008 R2.

Check nTMixedDomain, should be 0.

Is the new server part of the current/relevant domain? Have joined this server with the current domain? I assume that you have a DNS and AD server already in place and running properly. Check your DNS server for an entry for the new server, if it not there you may want to add it. If it should have been there, then check your steps and try again.

I would not put it past bad media as you suggested. I have actually had that happen to me before( with other products) so if you are in doubt that take that course of action.

Download Exchange 2010 SP2 fresh from the public download site and use that instead.
If you also download the latest rollup for SP2 (4 at the time of writing) and put it in the Updates directory of the extracted download file, then Exchange will install that as well.

Bad downloads of the ISO are very common, I don't actually waste my time with the ISO download because the only difference is that the ISO has all of the UM languages which are not required for most customers.
