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.
