I am trying to install Exchange 2007 sp1 on a new box running Windows 2008 x64. When I run the Exhange 2007 readiness check, I get the following error message? "permissions inheritenance block on server container object admin Group First Admintrative Group" I am currently running Exhange 2003 server on a different box with the same domain. I would appreciate any help or guidance to solving this problem. Thanks
