This weekend I will be re-installing server 2008 r2 on a box. Only doing a re-install to make my c: primary partition larger in size. I will be re-installing on the same exact hardware, be naming the computer and domain controller the same etc. So I have a couple of questions before I get started on it this weekend.
1. Can I some how export my active directory users/groups and then import them once the operating system and DC is setup?
2. Once things are back up and running, and either I'm able to import users/groups, or have to create the OU / groups / users again, when those users log onto their machines Monday morning I'm guessing they will have a new profile on their machine? I should then be able to copy/paste from their old profiles on their machines for the desktop items, my documents items etc? All usernames will still be the same and OU setup the same as before. *I just know people will freak coming in on a new day and their desktop is gone basically*
3. I have a D: partition on the same drive that will be wiped out when I re-install. I use this for storage basically. If I copy this to a new external drive will the folder permissions stay with it? So only certain users have access to the share etc? I am guessing I will have to manually re do all the permissions?
