I have just a domain in my forest and have an exchange 2007 sp1 on windows server 2008 sp2.
I want to upgrade to Exchange 2010 with coexistence with exchange 2007 and after moving all mailboxes I will remove exchange 2007!!
First of all I should upgrade to exchange 2007 sp2 or sp3.
When I run setup.com /prepareschema or /prepareAD or /PrepareLegacyExchangePermissions in all of them it get an error message :
C:\Users\administrator.PMP\Desktop\exchange 2007 sp2>Setup.com /PrepareLegacyE
Welcome to Microsoft Exchange Server 2007 Unattended Setup

I have run this command on master DC (windows server 2008 sp2)that has all fsmo rolles.
Could you please help me how I can pass this error correctly!!??
