Urgent Question about replication

[Hedghog]

I have two servers one running as primary and the other as backup their respective operational master roles are primary - RID and PDC and the standby is set as infrastructure operational master role.

 

Now I made a mistake which upset AD but I thought well Ok I have a backup. restored the back having shut the standby server down and restored system state. All checked ok but as soon as I restarted the standby server it all went pear shaped AD was back to where I left it.

What have I set wrong.

By the way the standby also provides DNS and DHCP for the Domain.

what did you do wrong with AD in the first place?

[Hedghog]

deleted an OU in error (the staff OU)

What i would do is demote the backup DC to a member server. Then restore the backup on the main DC then promote the backup one to a DC again.
