complete fault tolerance....
|
|
|
| i have a domain controller.
is a simple server p3 933 mhz with 512 mb of ram.
the server is win2k, have dns active directory integrated, dhcp and AD.
only one OU is created and the server provide service to only 10 users.
i want to provide some kind of fault tolerance. i install a 2nd server. i add this 2nd server as a 2nd domain controller for the domain. all the replica is finished and everything is working fine.
i add dhcp service to this 2nd server too. and i implement a 50/50 rule.
now active directory and dhcp is fault tolerant. but what about dns?... what step i must follow to add a 2nd dns on the 2nd server as active directory integrated. sorry for the stupid questions. i donīt want to make a test here, i only want to implement and i want to follow the expertise recomendations of people on this forum | |

| All you need to do is create another zone and make it Active Directory integrated. That way the DNS zone files are replicated with AD. | |

| Just so you don't have a misunderstanding:
On your new (2nd) server, add the DNS service, add a Active Directory Integrated zone that corresponds to the one on the first server.
Your first server already has an Active Directory Integrated zone, you just want to make a replica to that one that is AD Integrated as well. | |

exactly this is my doubt:
in the 2nd server i can add the dns service, and when i want to add the active directory integrated zone, what steps i must follow?. in the case of primary or 2nd zones i donīt have problems. i donīt have problems converting to AD integrated, but my doubt is the replica and the creation of the zone when is a replica from anothe dns server, just like in this case...
sorry, by now i donīt have 2 systems at home. only one..... let me check if i can use a laptop for some testing......
thanks

| For 217 it really helps to have two computers running server, for this reason and so so many more... | |

i know.... i finish the domain test controller and i'm adding a 2nd partition to a p4 latptop to install a 2nd one....
but advise is required!!! | |

| Good job, gotta go with what you got. More exercise in fault tolerance. | |

the first domain is finished.
have win2k adv server with sp3, dns and ad with their srv, some OUs and some users, GPOS activated, etc........
I get the 2nd laptop and now iīm using partition magic to resize the 1rst partition and move the 2nd one. after i move the 2nd partition, i have 3 gb free space at the end of the hd to create a new partition and install win2k server for the 217 testing.
what kind of testing i can make after i have dual dc? | |

| Replication, tranferring FSMO roles, DNS delegation and much more. All important for 217. | |

ok.
was a nightmare the win 2k server laptop preparation. the latop had 2 parition with win xp home and xp pro on this 2 partitions. i need to resize and add a 3rd partition. i was unable tu install for several reasons. the 3rd created partition was corrupted and i need to make a lot of things like install perfect disk to clean the partition, etc etc. after install 2k server, the boot files on the boot partition was replaced by 2k and any xp OS was unable to start. as i see this problem before, i replace the 2k files with xp files and now i have a triple boot laptop working installed using bad order.
i lost lot of times looking for the drivers for the network card because the drivers are included with XP but i only find a site on the internet with this drivers.
but now everything is working and sp3 is installed.
in few minutes i start the "fault tolerant domain" testing!!!!!!!! | |

| Good luck, keep posting questions and comments... | |

| On each DC after the original one, you have to make it a GC. As far as FSMO roles, only one schema master and one domain naming master per forest, one pdc, rid and infrastructure master per domain. It's up to the designer to place these in the right areas and provide well replicated partners in case role transfer or siezure is needed. | |

i can have more than one GC? | |
| jeff_j_black 2002-10-28, 9:08 pm |
| You may add as many GC as you like, just know that additional replication traffic will result. | |

so what is your recomendation for a fully fault tolerant domain if now i have a dual dhcp / dual dc / dual dns ad integrated?... what steps i must follow or what i must do?---- | |
| me? I dunno... 2002-10-29, 10:54 pm |
| If forests are only fault tolerant to the extent of global catalogue info, (I think?) then backing up between domains and perhaps even forests might be the ticket?
Is that how it's done? | |

| If you have a SINGLE domain, then all your domain controllers are in effect Global Catalog servers. Because there is only a single domain, it is not possible to have information in one domain controller that is not in another domain controller.
3 parts of Active Directory. Schema Partition, Configuration Partition, and Domain partition. In a multiple domain/tree forest, all domain controllers will have the same Schema and Configuration partitons, whereas only the domain controllers within the same domain will have identical domain partitions. The global catalog servers will have references to items from additional domains for faster searching.
Currently, the only exception to this is if you are using Universal groups in native mode. However, if you have a single domain, it is not wise to use Universal groups as global groups would provide the same benefit with less overhead. | |
