Restore AD from another dc

lost a secondary dc at another site (mpls connection).  There was no backup.  So, i have the server up and running with fresh 2003 install.  I have read of using a server state backup from another dc (primary in this case)  to restore to another box.  I tried this and now the box seems to think it is the dc it was restored from (same computer name).  

What would be the right way to restore AD to another controller?

Hi,

you are right,  a System state backup from another dc can be restored to another Dc.

Do the following.

1. Install the OS on other machine and update it with latest patches.
2. Restore the "System State Backup" on new folder or different location.
3. on new system, Go to run and type "DCPROMO /ADV" and press enter.
3. follow the screen you will get the option to promote the domain controller from backup.

Could you explain why you would do a restore?  The simpler, easier, and frankly, in my opinion, LESS RISKY solution is to simply remove the failed DC from AD and rebuild it as a secondary.

I guess i do want to rebuild a secondary but wish to get the AD into it because the primary is 100 miles away with not much MPLS bandwidth.

How many users?  AD Replication shouldn't take all that long for a small network (by small I mean under 500 objects).

Even on a low bandwidth connection, the replication time shouldn't be bad.  I really wouldn't be concerned about it.

Ok.  i guess i should delete the failed dc from the domain, then promote my new one in it's place?

That would be my recommendation.

Just assuming you do things appropriately - NTDSUTIL to clean up the Metadata, seize necessary roles, etc
