Active Directory will not work after Disaster Recovery Restore Using Backup Exec 11d

I am in the process of migrating a customer's server over to new hardware. After hearing good things about Symantec Backup Exec 11d I installed a trial version, performed a full backup and created a Disaster Recovery CD. (All through wizards, no errors, pretty simple) I backed the data up onto an external USB HDD.

After a bit of trial and error on the new kit I have managed to get the backup restored using the following method
1: Run DR CD and restore backup. ( I had to install LAN drivers for the new mobo and a couple of Hotfixes 925902 & 930178 )
2: Restart Server and boot to Recovery Console. Remove Hotfix 931784 - This was causing the server to hang. I found this through a LOT of trial and error.
3: Server restarts and boots to the DR O/S one last time for about a minute to finish off and restarts into Windows.
4: Reactivate Windows due to hardware changing
5: Install drivers for new motherboard (I did have to re-install the LAN drivers which I did before ?)
6: I reinstalled KB 931784.

Now the problem I have is with AD. If I go into the server management console there are no users, computers, servers or printers listed. If I open the AD users and computers utility in Administrative Tools I get a pop-up saying "Naming information cannot be located because: The specified domain either does not exist or could not be contacted. Contact your system administrator to verify that your domain is properly configured and is currently online"

If I run DCPROMO the server identifies itself as a DC and a Global Catalog server.

Do I have to do a further restore through Active Directory Restore mode , or some fiddling about with NTDSUTIL ? AlI the DNS settings seem OK. I have configured a router and the new server  IP to be the same as on the old server.

I would contact Symantec Support but as its not a full product they want to charge me.
