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

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.

You need to first off, make sure that the 2nd DC can fulfill all the
functions of the 1st one (DNS, DHCP, etc.). 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.
