2008R2 Demote DC & Repromote best practice
Posted on 2013-01-29
I have 2 x 2008R2 servers with AD server roles.
the secondary one (SERV2) has gone into USN rollback state from what i can google.
The Active Directory Domain Services database has been restored using an unsupported restoration procedure.
Active Directory Domain Services will be unable to log on users while this condition persists. As a result, the Net Logon service has paused.
Will have to ask the other IT support if they had to do this before xmas when making some other changes to this system. May be causing some logon issues.
the primary (SERV1) has all FSMO roles. (netdom query fsmo)
SERV1 has AD, App, DHCP,DNS,Print & WebIIS roles. (and is the main intranet server)
SERV2 has AD,DNS,FileServ roles.
what is the best / quickest way to resolve this as the secondary machine is also the file server so repeated reboots can cause interuptions.
is removing the AD role from Serv2 , reboot , Add AD role and reboot the best way to clean up the mess ? or is dcpromo from command line more appropriate ?
