recovering a DC

[James]

Hello,

I have a window 2000 DC with corrupt registry (it is not the pdc). Is there
a way to recover the server and active directory by a parallel install? if
yes, how? thank you in advance.

have you got a System State Backup from _this_ Server ?
If the Server is only a DC, then you can demote your DC from the domain with
DCPROMO, install the server new and then promote your server in the domain
again with DCPROMO.

Thanks for the reply,

The server is only a DC and is not bootable at this time. Also, there is no
good backup for the system.

Then you`ve got no chance and you must be install the server new.
But first, you must be clean the Active Directory from the old DC:

Then you can promote your Server in the domain again.

I would:

1) Verify that all FSMOs are on the other DC's
2) Verify that all other functions like DNS, DHCP, etc. are on the other
DC's
3) Shut the bad DC down and verify that the network functions normally
4) DCPROMO to a member server
5) Remove from the domain
6) Verify whether a meta data cleanup is necessary
7) rebuild the server
8) DCPROMO it back

Hi



- Transfer any fsmo roles olded by the servers to be removed

-Make sure that you have at least one GC on your forest.

- Transfer any other services that you might have on the old DC (like;
DNS, DHCP, Wins, DFS, etc).
- Take the old server offline; confirm that everything works with the old
server offline.
- If everything OK, use Dcpromo to remove the old DC from network, (Ps:
don't
forget to remove it manually from Active Directory Sites and Services)
