Hi guyz,
Today i decided to make a process to follow in case of Domain controller failure. And i found a big trouble on my domain.
So here are the domain configuration.
2 domain controllers
DC1 name: Billisgay
DC2 name: whatsupguyz
The domain is in Native Mode (only W2K DCS).
When i started to implement that domain, i began with DC1 installation. At this point, i configured my dns, created all users accounts, and lots of others stuff.
I decided to add a spare DC, so i transfered 3 roles on that one (RID, PDC emulator, and infrastructure).
Now the configuration looks like this:
DC1
- domain naming master
- schéma master
DC2
- rid master
- pdc master
- infrastructure master
Some times after, I tried to make some DC failure simulation. I cut DC1. then , DC2 is still able to let users log on the domain. So no need for me to be afraid.
But when i did the same test with DC 1, that has only 2 schema roles. Users cannot log. I cannot add another DC to the domain and cannot add a new computer to the domain too. Seems it is normal, since PDC role was not available, so i decided to seize the 3 roles that were on DC2 to take them back on DC1 (as on original configuration). It seems to happen very well....hem Windows tells me that DC is informed of the 5 roles, and that they are located on himself...
But when i ran DCDIAG and NEtdiag, they told me, that PDC roles is not available, and so on, No primary domain controller available too.
This explain the fact i cannot add comp to the domain.
It is not due to my dns conf, because DC1 and DC2 uses rhe same one. SRV are here, and DC are known by the dns (and so on by the clients). I cannot understand why the role is not available since i transfered all of them...
Someone told me that it is normal because DC1 was the owner of the roles at the first time, and it cannot be given back from DC2 to DC1. I have read a white paper on MS site, which explains that it is possible to transfer roles, especially the PDC....
Can anyone give me an answer to that dilemma?
Thanx in advance .
