We have to sites A and B and in B which is in another state they already communicate with A. Site B were shutting off two DC's (win server 2008 r2) they are DNS, & Global catalog servers and dhcp with no fsmo roles of which are handled by Site A main domain controller.
Were using Intersite replicaiton between site A and B what do I need to do?
My question would be how should I do this
* Dcpromo before shutting down
* Shut them down and then dcpromo /forceremoval
Do users at site B have to log off then back on to authenticate to domain controllers at site A?
All I want to do is remove these two servers and need to know the best way so that users in site B are able to logon and authenticate like nothing happened.
