  • Active Directory Failover

    Dear All,
    I had a Windows 2003 R2 Server Standard SP2 DC; I call it DC1, which was also DNS & DHCP Server.
    I also installed new Windows 2003 R2 Server Standard as additional DC (without DNS & DHCP Server), I call it DC2 and I check on AD Info has replicated correctly.
    But when my DC1 down, all of my computer unable login to AD, is that once the DC1 was down then DC2 will take roles.
    Could anyone kindly help me on this matters, how should I design the AD where it can be failover.
    Thanks in advance,
    Regards,
    Eric

    Eric,

    First thing I would suggest would be to install DNS on DC02 and make sure eash server/client has both servers listed in there DNS settings. Second, if you are running Exchange in your environment add DC02 as a global catalog server (it is not mention, but I am assuming you are working in a single forest/single domain environment).

      And, just in case, add DC02 as a DHCP server, splitting the scope between the two servers
