After you use Ntbackup.exe to perform a full restore or a full System State restore to restore a Windows 2000 installation over a clean Windows 2000 installation, the network adapter may be missing in Device Manager. Instead of the correct network adapter, a new device, such as a WAN miniport (L2TP) device, may be listed. You also might not be able to reinstall the network adapter.
This behavior can occur if the deployment method that was used to install the clean Windows 2000 installation differs from the deployment method that was used to install the original installation.
Before you perform the restore operation, you must reinstall Windows 2000 by using the same deployment method that was used to install the original installation. For example, if the original installation was installed by using the Windows 2000 CD-ROM, you must install the clean installation of Windows 2000 by using the Windows 2000 CD-ROM. If the installation was originally installed by using an unattended installation script, you must use the same script to install the clean installation. After you perform the clean installation by using the same deployment method, you can perform the restore operation.
You might also be able to work around this behavior with an in-place upgrade of Windows 2000 after you perform the restore operation. For additional information about performing an in-place upgrade, click the article number below to view the article in the Microsoft Knowledge Base:
