Disaster strikes and I lose my servers completely, but I have a tape backup of the complete system drives (C:) and the system state of the servers. Now, I purchase new servers (most likely not identical, hardware-wise, as the old ones) and the same type of tape drive so I can read my backup tapes. I install Windows 2000 on the new server with just the default settings with the same machine name, and then restore the system drive and system state to the new disk using the NTbackup with selection "original location, restore security, restore junction points and always overwrite existing file." Everything seems to be there and somewhat working, but not clean.
I can't figure out why. I restored it non-authoritatively and authoritatively (using the NTDSutil), but I'm still having the same problem. I also saved the boot.ini and hal.dll file and renamed them before I restored the save set so I could switch back if I want to for testing, but it made no difference. All the data for Active Directory shows up and the operations manager is pointing to the right machine and domain name, but when I click on some users or DNS properties, it hangs. I would say it is timing out or looking for some connection or domain, etc.
At this point, I am not connected to any network since it would be my first server and I am just starting to rebuild my network. Is there a way to change the DNS to primary (file replication services)? I checked under the SYSVOL folder but could not find any settings. It looks to me like it is waiting or trying to communicate with another domain or waiting for an outstanding I/O.
First, a full restore to a system that is not identical hardware-wise to the original will never fully work as expected. If you are even able to complete the restore and boot the system, I recommend performing a repair install and re-applying the latest service pack. Even then you may not get a fully functional machine. Remember that a big part of the OS is built based upon the hardware components (i.e., CPU, motherboard, memory, drive controllers, PCI slots, USB, etc.) and the system does not take kindly to changes to the core elements.
I suggest building the new system from scratch and restoring just your data files. Then fully reconfigure the new system to meet your needs. In the future, only attempt a restore to duplicate hardware.
