I have had some questions about once you do the migration how do i get the users to show up in the SBS 2008 Console. Here is my reply to one of those questions and hopefully it will help those that is looking for this answer.
“In your SBS 2008 Console go to Users and then over to the right you will see “Change User Role for user accounts” select this and then this will start a wizard. Select Standard User and “Replace User Permissions or Roles” hit next here you will see the users on your SBS 2008 Server but if you check the box that says “Display all user accounts in AD” this will show you your users you are looking for. You highlight the ones you want and add them and the wizard will do the rest. You will have to do this for the ones you want as Standard users and also again for the ones you want to have Administrative permissions. Also if you are wanting your computers and Servers to show up in their respective lists you add these to the SBS Computers and Servers OU’srespectively and then they will show up in your SBS 2008 console.”
Til later just Roger
