How to demote a DC server crashed
Hi,
one of my DC server crashed (motherboard) last monday and I unfortunately can´t recovery this server.
I´m mounting a new server (new name) and restoring the data of the crashed server in it.
Well, my problem is that I need demote the crashed server but I can´t use DCPROMO in it.
How can I demote it?
Another problem is that the crashed server was a root domain DFS. Is it possible demote this DFS too? I need create this DFS in the new server.

Hi Thaaron,
I used:
dfsutil /clean... but dfsutil try to contact my crashed server and return a error: "system error 1168 has occurred" "element not found"
I try too:
dfsutil /rmftroot ...
and receive the message: "system error 1722 has occurred" "The RPC server is unavailable"
Another way?

Thaaron,
I removed using your sugestion but doesn't work. Then I stop the service DFS, and remove the registry entry HKLM\SOFTWARE\Microsoft\DF
Then I re-start the service and......finally I could create the dfs root.
Thanks a lot to jjdurrant, jared luker and you Thaaron.

I am not sure if this will help, but I have to use Mcrosoft Knowledge Bse Article # 216498 - How To Remove Data in Active Directory After an UnSuccessful Domain Controller Demotion.
In my case the server crashed, but I was able to use this article to remove the DC from the domain.

you can manually move the computer from domain controllers folder in AD to computers folder, and delete the computer from domain..and remove its replication link in AD sites and services. Then delete all dns records of this computer. Now your PDC will no longer try and replicate and the server will be non-existent in AD or DNS...and remove WINS replication if you have WINS server.

thanks for the answer. I already seized all fsmo rules (using ntdsutil) and removed the crashed DC from Active Directory using "Active Directory Users and Computers" (del in the crashed DC).
DFS: My AD is ok in another DC, but when I try to show the DFS root I receive "the RPC server is unavailable".
If I try to create another root with the same name (i need to do because i don´t want to change all my users network map) i receive the message: "the DFS root my_dfs_name already exist..." and I can create this root.
Please help me.
