Guest Luca Rossi Posted October 20, 2008 Posted October 20, 2008 Hi to all, for the first time (for me...) i have to demote a domain controller for a complete reinstallation, actually DCs are two. The question is: have i to pay some attention to particular settings before follow "dcpromo.exe" tool ? What happen to users logged in the domain ? After reinstallation, this server will be promoted as DC with the other one.... Thanks in advance Bye Luca

Guest wakaman Posted October 20, 2008 Posted October 20, 2008 Re: DEMOTE Hello Luca, Since you have two DCs, just make sure that they both up to date with replication. If no replication errors, then you can safely demote one of them. There should be no issue with users that are logged on to the domain, they will not even realized that one of the DC is offline. I am assuming that the 2 DCs are in same domain. Yes, after reinstallation the dc will just replicate its sysvol from the the existing dc. and all your domain data will be intact. Just make sure you demote and repromote one DC at a time. Make sure the new one is functioning well before you start reinstallation of the other one.

Make sure that you transfer all the FSMOs to the 2nd DC (it must be a GC). When you DCPROMO the 1st C, it should automatically transfer them to the other one, but most of us would recommend doing it manually. I would suggest taking the 1st DC off line for a while and verify that there are no problems. Then DCPROMO is and rebuild. There should be no impact to users already logged (assuming that the DC is just a DC). I reboot my DCs routinely when there are Windows updates. The only one I have to worry about is one that functions as a VPN server. I have to make sure that no one has a tunnel open to it when I reboot. -- Regards, Hank Arnold Microsoft MVP Windows Server - Directory Services
