Windows 2003 DC failover
Posted on 2012-03-29
I have a single domain Windows 2003 network with redundant domain controllers. if the first DC in the domain were to die irreparably would one of the remaining DC's fully take over and which one would it be - the second one installed, assuming I have three, let's say? If the DC that died just did DC - no other services - would anybody notice? Would I have to do something to the other DC's? If it did have services such as DNS or DHCP would I have to have had the other servers having 'secondary' versions of them and then again if the 'first' one died would the secondary ones take over so that nobody would notice? Or would I have to do some additional work? The basic question is how transparent is DC redundancy? Is there ever a need to try to restore one - same name/same function - if I have other DC's - or can I just blow it away?
