When I attempt to install the new beta, currently running build 7000, it wants to uninstall build 7000 wiping out that data and setups. How do I go about getting the new version installed. Also, does the new build include Exchange support? One of the issues I have is that on Domain controllers, the domain authentication works for getting the AD information but fails on the WMI services. If I remove the domain from the auth credentials, the WMI works but the AD fails.
