Hi, i have created below thread reported 'PrepareAD' command can not run successfully, but i was force installed Exchange 2007, it's very strange, i am sure the 'PrepareAD' commnd was not excuted successfully, but Exchange 2007 seems installed into my Virtual Machine. After installation, i checked below things. 1) 17 exchange services installed as expecting. 2) a new OU named 'Microsoft Exchange Security Groups' appears at 'AD users and computers'. any updated information, that a lot thanks. Jiao
