Hi, Here are first steps ...on a child domain Windows 2008 is ready installed with everything is ready to use and to install Exchange 2010. Eveything is ready to use the first step: FIRST step: • setup.com /PrepareLegacyExchangePermissions • setup.com /PrepareSchema • setup.com / PrepareAD (if I use preLegacyExchangePermissions I don't use this command) • setup.com / PrepareDomain Regards, deliyurek007

Hi, The command are good! But It's recommanded that you execute the - Setup.com /prepareAD on the site that hold the schema master role - If you have one domain you can execute setup.com /prepareDomain Using this two commands on one domain controller that holds the schema master role is recommanded. No need to execute those command on all domain controller! Don't forget that there the famous Active directory replication. Hope that helps you !! Best Regards Don't forget to mark it as answer if it helps

For a single domain you don't have to run the prep commands - just run setup.exe and follow the prompts. The installation tool will prep the domain for you. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.
